The foot has a complex structure and most people take a million or so steps a year, so it’s not surprising the feet can be prone to arthritis and related problems.
The main causes of foot pain are:
Seek help if you:
Most people will be able to care for their foot pain themselves. If needed, specific treatments include:
If you see a rheumatologist, GP or nurse regularly, you can ask them who else you could see. This may be a:
They have a complex structure consisting of 26 bones, more than 30 small joints (where bones meet) and many muscles, tendons, ligaments and nerves. Problems in the feet and ankles are often, but not always, associated with arthritis. Most feet have an arch shape that spreads the body’s weight evenly over many bones and joints. Feet with lower arches tend to be more flexible, while feet with higher arches are generally less flexible. High or low arches aren’t necessarily a problem but they can increase your chances of developing other foot problems.
The structure of the foot changes as we get older or if arthritis affects the foot joints, and many people will notice changes, particularly in the arch of the foot.
The feet and ankles can be affected by several types of arthritis, including osteoarthritis and inflammatory arthritis.
Osteoarthritis can affect any joint in the foot. Osteoarthritis is a chronic problem that may cause episodic joint pain and joint swelling, and bone enlargement. As people get older, osteoarthritis can be linked to changes in the shape of feet, which may cause pain.
Osteoarthritis often affects the big toe joint. The joint will become stiffer and the range of movement will be reduced. Often the bones become larger and knobby due to an overgrowth of new bone. These changes may accompany a bunion (a lump on the side of the big toe joint). You may also notice a bunionette (a lump on the side of the little toe joint).
Recent findings suggest that osteoarthritis is more common in the arch area of the foot than previously thought. Osteoarthritis can also develop in the ankle, but this is usually following a previous injury or damage to the joint from long-standing inflammatory arthritis. Osteoarthritis in the feet often accompanies osteoarthritis in other joints
There are various forms of inflammatory arthritis, which can affect the feet in different ways.
Apart from problems in the joints themselves, people with inflammatory arthritis may have inflammation and discomfort in the tendons and the other soft tissues in the feet. The part under or behind the heel where the tendons attach to the heel bone (the Achilles tendon) is quite often affected in this way.
Dactylitis causes pain and swelling, usually in just one or two of the toes (‘sausage toe’). It’s commonly associated with psoriatic and reactive arthritis.
Gout is a very painful type of arthritis. It’s caused by the formation of crystals in a joint. It often occurs in the foot, and the big toe is the most commonly affected joint. The joint will be red, hot and swollen during an attack, which typically last one to two weeks. Without treatment, repeated attacks can cause permanent joint damage, leading to osteoarthritis. Gout can usually be controlled with medications.
Raynaud’s phenomenon is a circulatory problem that causes the blood supply to certain parts of the body to be reduced, especially when exposed to cold conditions. It more commonly affects fingers, but it can also cause toes to go temporarily cold and numb and turn white, then blue, then red. These attacks often only last a few minutes, and moving into a warmer environment often stops the attack.
Wearing warm socks may help to prevent an attack. Raynaud’s phenomenon can occur with the conditions rheumatoid arthritis, scleroderma or systemic lupus erythematous (SLE).Watch out for ulcers on the toes, or a colour change which doesn’t go away as quickly as usual. These problems are usually very painful. If you develop one of these symptoms, you should see your doctor or contact your rheumatology nurse specialist as soon as possible.Sometimes with lupus the joints and tendons are affected and you may notice that the toes drift outwards and the arches may flatten. This can be painful and may cause a feeling of stiffness after periods of rest.
Pain in the ankles and heels can come from the joints themselves or muscles and tendons around the joint. Osteoarthritis isn’t very common in the ankle but can be the result of previous damage from an injury or due to inflammatory arthritis. When inflammatory arthritis affects the ankle, the joint may be sore or stiff first thing in the morning or after sitting for a while.
Valgus heel is commonly associated with tendon damage on the inside of the ankle and arch; this can cause the heel to drift outwards. This is known as valgus heel. It may not cause any problems if it doesn’t drift too far, but it can be troublesome if the arch flattens. It’s fairly common in people with rheumatoid arthritis and research has shown that early treatment of rheumatoid arthritis may slow the development of valgus heel.
Also known as plantar fasciitis, this is a degeneration and/or inflammation at the heel, where tendons and fascia that attach under the heel bone cause pain. It used to be known as policeman’s heel and is the most common cause of discomfort around the heel. Plantar fasciitis frequently affects people aged 40 to 50 with active occupations. It can be associated with inflammatory arthritis.
Research has shown that plantar fasciitis is sometimes caused by the shortening of the Achilles tendon and that exercises to stretch it usually helps. Losing weight and wearing insoles to provide cushioning in your shoes may ease symptoms. A steroid injection can help but they’re not recommended as a first resort.
Also known as Achilles tendinitis, this is an inflammation of the Achilles tendon at the back of the ankle. It occurs as an over-use injury in people who take part in excessive exercise or exercise they’re not used to (i.e. marathon runners). It’s also found in people who have psoriatic arthritis, reactive arthritis or ankylosing spondylitis.
The arches of the feet allow the weight of the body to be spread over many bones and joints. The arch structure can change when it’s affected by arthritis, and the structures nearby can be strained. In mild cases this feels like tiredness in the arch area, but it can be more painful if the muscles or tendons are overworked.
Some people find arch supports or foot orthoses helpful for arch pain or tiredness.Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, can help with arch pain, and a local steroid injection may ease more severe pain. Sometimes you may find an anti-inflammatory gel applied two to three times per day can help. You can buy this in chemists and supermarkets. Anti-inflammatory tablets should be taken when a number of joints are painful.
Having higher arches (pes cavus) may increase your chances of developing other problems such as hammer toes, bunions, corns or calluses. Lower arches (pes planus) are sometimes linked to leg problems, especially knee cap pain.
Pain can be caused by arthritis in the joints at the ball of the foot, especially if you have arthritis elsewhere. However, most pain in the ball of the foot comes from minor damage to the soft tissues – tendons, bursae, fat pads, nerves and skin.
The most common causes of discomfort under the ball of the foot are calluses (a build -up of hard skin) and corns. Calluses form at areas of high pressure or friction and typically cause a burning pain. If pressure is extremely high, small areas of skin within the callused area produce an abnormal type of skin tissue, leading to the formation of a corn.
Bursae are pockets of fluid that cushion joints and tendons. They can become inflamed under the ball of the foot and cause pain, particularly if wearing high heels or tight shoes, or by doing too much weight-bearing exercise. People with rheumatoid arthritis often develop new and large bursae under the ball of the foot. Bursae can grow and shrink as the level of inflammation varies. They also occur next to large bunions or other irritated joints.
Treatment for an inflamed bursa starts with reducing the pressure on the area. If it’s large, especially inflamed or you’ve had it for a long time it may help to have fluid drained and a steroid injection.
A neuroma is a thickening of a nerve, which occurs when it rubs against other nternal tissues. It’s most common at the base of the toes, often between the third and fourth toes. The symptoms are sudden pain and/or tingling in the toes.
A neuroma should settle down with more roomy footwear, but special insoles or pads under the area may help. These may be available through an HCPC-registered podiatrist or orthotist. A local steroid injection may be recommended and, if symptoms are severe, the thickened nerve may be surgically removed.
In rheumatoid arthritis, firm, pea-sized lumps can occur at pressure points such as the big toe joints, the back of the heels or on the toes. Nodules on the soles of the feet can be particularly uncomfortable. Padding can ease the discomfort but, in some cases, the nodules may need to be removed surgically.

For most people foot problems can come and go without any prescribed treatment, or can respond well to self-treatment.
However, if you have a known condition such as rheumatoid arthritis, scleroderma or diabetes, you should discuss any new foot problems with your rheumatologist, your GP or a podiatrist.
Even if you don’t have any significant health conditions you should still seek help if your foot problem:
You should also seek help if you develop foot problems and you have increased swelling, you’re on drugs which suppress your immune system (including steroids or biologics) or if you have a history of poor skin healing.
In most cases a simple clinical examination is all that is required. This usually involves looking carefully for signs such as swelling, combined with a short hands-on exam to work out which structures might be involved. Sometimes it is helpful to have the person walk up and down to see what happens during weight-bearing and routine activities.
It is less common for foot problems to require blood tests or imaging (e.g X-ray or ultrasound) to reach a diagnosis.
A regular foot care routine can help to keep problems to a minimum but seek advice from your doctor or a podiatrist first; especially if you have conditions such as vacuities or scleroderma, you’re taking steroids or biologics, or your skin is slow to heal. The routine should include regular nail cutting, filing the skin and applying appropriate foot care cream. Choosing the right footwear is important.
Exercise is important to keep your joints moving and helps you keep to a healthy weight. Losing weight if you’re overweight can be difficult, but will help ease pressure on painful feet. Swimming and other non-weight-bearing exercises are best if painful feet make exercise difficult. An HCPC-registered physiotherapist or podiatrist may be able to suggest exercises.
If your ankles feel stiff in the morning, allowing some time for the joints to loosen up will usually help. Warm water from a bath or shower can ease stiffness. During the day, alternate between sitting and standing activities to take the pressure off the feet. Resting for 10 minutes at a time throughout the day can be helpful, especially if you keep your feet raised. This is particularly useful if you have plantar fasciitis or swollen ankles.
You may need to take special care of your feet if you have arthritis, either because of the condition or because of the medications you take. A good, regular foot care routine will usually keep problems to a minimum:
If you have rheumatoid arthritis, you should have your feet checked by a professional just after your diagnosis and then once a year. This can be done by your GP, rheumatologist or nurse, and if you have problems you should be referred to an HCPC-registered podiatrist. Some people with rheumatoid arthritis have a burning sensation in their feet at night. Using a hot water bottle filled with cold water can help but you should speak to your doctor about it, especially if this is a new symptom.
Calluses can usually be scraped away using a pumice stone or abrasive board. You should never use an open blade such as a scalpel or razor blade. Special skin files and scrapers may be suitable as long as you and your skin are in good health, although these will not help much with corns where the nucleus goes deeper into the skin. Check with your doctor or an HCPC-registered podiatrist first, especially if you have a history of skin ulcers or suffer with scleroderma, vacuities, lupus or Raynaud’s phenomenon.
Pads and cushions available from the chemist may help with painful pressure points, but over-the-counter creams and medicated corn plasters aren’t generally recommended. If you’re on steroids or biologics, have vacuities or your skin heals slowly you should avoid these treatments altogether.
If you can’t care for your feet yourself, your GP or hospital consultant can refer you for professional care within the NHS. Podiatry services accept patients on a self-referral basis. An HCPC-registered podiatrist will help with troublesome nails, corns and calluses, and they’ll provide advice on finding special shoes or orthoses. Some centers have access to an orthotist who will be able to assess and provide ready-made or custom-made shoes as required.
Most foot problems will be helped by finding footwear that has more room and is more comfortable, and by losing weight if you’re overweight. A number of specific treatments can also help:
Non-steroidal anti-inflammatory drugs (NSAIDs) can help to relieve painful inflammation, for example in the arch or heel area. Like all drugs, NSAIDs can sometimes have side-effects, but your doctor will take precautions to reduce the risk – for example, by prescribing the lowest effective dose for the shortest possible period of time.
NSAIDs can cause digestive problems (stomach upsets, indigestion or damage to the lining of the stomach) so in most cases they will be prescribed along with a drug called a proton-pump inhibitor (PPI), which will help to protect the stomach.
NSAIDs also carry an increased risk of heart attack or stroke. Although the increased risk is small, your doctor will be cautious about prescribing them if there are other factors that may increase your overall risk, for example, smoking, circulation problems, high blood pressure, high cholesterol or diabetes. Insoles (orthoses), sometimes used with special shoes, can relieve arch pain or tiredness and help to correct less severe cases of valgus heel.
A steroid injectionmay be recommended if just one or two joints are inflamed and painful, and it might help inflamed tendons or bursae, neuromas and plantar fasciitis. You’ll need to rest the foot for up to 48 hours after the injection to get the best result.
Disease-modifying anti-rheumatic drugs (DMARDs) are prescribed for some people with inflammatory arthritis. They alter the underlying disease rather than treat the symptoms. They’re not painkillers, though they’ll reduce pain, swelling and stiffness over a period of weeks or months by slowing down the disease and its effects on the joints. A common example is methotrexate.
There are a few foot-specific points to consider in relation to biologic drugs used to treat inflammatory arthritis such as rheumatoid or psoriatic arthritis. First, if you have persisting foot involvement while on other disease modifying anti-rheumatic drugs (DMARDs) you should discuss with your rheumatologist or nurse the options for starting a biologic. Often the feet are inadvertently overlooked.
If you’re already on a biologic there are a few other considerations you’ll need to bear in mind. Because biologics suppress the immune system, you need to be aware of the effect of biologics on infection. We don’t think biologics make a difference to the overall risk of infections in your feet, but biologic use does seem to make infections take hold more quickly and cause greater trouble. If you’re on biologics do not use corn plasters or skin scrapers and if you do have an ulcer or infection make sure you let your rheumatologist know as soon as possible.
In some people starting a biologic drug can result in a big improvement in joints in the upper body but problems can persist in the leg joints – we think this is because these weight-bearing joints may have already been damaged. If you do have ongoing aches and pains in feet, ankles and knees after starting biologics, again let your rheumatologist or nurse know. There are often additional treatments that can help.
Surgery is sometimes recommended to improve the structure of your feet. If other treatments haven’t helped, surgery may be suggested to:
Joint replacements for the ankle and foot aren’t yet as successful as replacement knees and hips. Most foot surgery is aimed at correcting the positions of the joints by resetting the bones or fusing the joint in the corrected position. Your surgeon will discuss the potential pros and cons of all the available options before you decide to go ahead with surgery.
Therapeutic massage can help to reduce pain or tiredness in the feet. Massage can be combined with a relaxing warm-water footbath, and both of these are fine as long as you don’t have any open wounds or sores on your feet. The effectiveness of treatments such as acupressure sandals and magnetic insoles isn’t supported by evidence.
Generally speaking, complementary and alternative therapies are relatively well tolerated, although you should always discuss their use with your doctor before starting treatment. There are some risks associated with specific therapies. In many cases the risks associated with complementary and alternative therapies are more to do with the therapist than the therapy. This is why it’s important to go to a legally registered therapist, or one who has a set ethical code and is fully insured.
If you decide to try therapies or supplements, you should be critical of what they’re doing for you, and base your decision to continue on whether you notice any improvement.
In most cases foot problems will not become persistent. Painful heels for instance can settle down spontaneously even after many months of causing trouble. Some foot problems though will go on to be persistent, osteoarthritis is a good example. If you have foot symptoms that have persisted for more than three months it’s worth seeking a professional opinion.
Getting the right footwear will make a difference for almost all foot problems and the importance of appropriate footwear should not be underestimated. A bit of trial-and-error to get the right footwear might remove the need to seek out professional help. Changes to footwear will be part of most professional discussions about foot problems. Comfort should be the main consideration when choosing shoes. High-heeled shoes or shoes that pinch your feet can contribute to the development of deformities such as bunions or hammer toes.
Your feet may change shape as you get older, especially if you have arthritis, so you may need to try a different size or width fitting. If the footwear protects your feet against injuries, supports them and keeps them warm, dry and comfortable, it’s doing its job.
An adjustable fastening will improve fit generally and help if the feet swell. Leather uppers are usually the most comfortable if you have foot problems although many modern materials offer breathability, flexibility and comfort. Look for a cushioning sole unless you’ve been advised by a doctor or podiatrist that rigid soles are better for your particular foot problem. If you have hammer toes or prominent joints, look for a smooth lining without seams. If you need special insoles or orthoses, make sure there’s enough room in the shoes to fit them, especially around the toe area.
Around the house, slippers may feel the most comfortable for hammer toes and prominent joints, but make sure the soles provide adequate cushioning. You should also make sure that they are non-slip/trip. Always wear shoes when you’re outside to make sure your feet are properly supported.
Have your feet measured if they’ve become wider over the years or have changed shape because of arthritis. Your feet may change shape when you stand up, so have them measured while standing. Many shops have experienced fitters. Try shopping later in the afternoon. If your feet tend to swell, they’ll be at their largest at that time.
Judge a shoe by how it feels on your foot and not just by the size marked on the shoe. Size varies between shoe brands and style. Think about how the shoe fits around your toes, under the soles and at the back of the heels.
Always buy your shoes to fit the larger foot – many people have one foot bigger than the other. An insole can be used in the other shoe. There should be at least 1 cm (3/8 inch) of room at the front of the longest toe.
Try shoes on with the type of socks or stockings you normally wear or with any insoles or orthoses you normally use. Some insoles may need extra depth, especially in the toe area.Don’t buy shoes to break-in later – the right shoes for you will be comfortable when you first try them on.
Buy shoes that have both leather uppers and inners (the inner lining), if possible. These are more breathable than inners made of synthetic materials and will help to avoid dampness and fungal infections.
Look for dark colours and a suede finish if you’re worried about the appearance of your feet – they’ll help to disguise the problem.
You may need insoles in your shoes for a number of reasons. An insole, or orthosis, can help to support the arch of your foot. If you have arthritis in the joint across the middle of your foot (the midtarsal joint), a rigid insole may help. If you have one foot bigger than the other, an insole can help to pad out the shoe of your smaller foot.
Insoles will often take up half a shoe size, so take along your largest shoes when you go for an insole fitting. Sometimes you may need to purchase a larger shoe to accommodate an insole, although this is not always the case. Take your insoles along when you buy new shoes.
If you need to wear a prescribed insole, don’t try to wear the new insole all day when you first receive it. Wear it for a short period at first and gradually build up to longer periods. Don’t use them for heavy duty activity or exercise. If you change your shoes indoors, either have a second pair of insoles for your indoor shoes or remember to swap the insoles over. Your feet will return to their old shape while indoors and will never be comfortable if you don’t continue to wear your insoles.
Insoles will often take up half a shoe size, so take along your largest shoes when you go for an insole fitting.
Lace-up shoes can be difficult to fasten if you have arthritis in your hands. Here are a few alternatives:
There are also a number of devices available to help people with putting on socks, tights/stockings and shoes. Useful leaflets on this and other subjects related to the feet and footwear is available from the Disabled Living Foundation or through your local occupational therapist.
People with permanently swollen feet, very narrow, long, or broad feet, or with hammer toes or bunions may find it difficult to find shoes that fit well. A number of retailers are beginning to stock shoes with extra width and depth, which can help. It may be possible to have high-street footwear adapted by an orthotist – ask them for advice.
Some people may have footwear prescribed by their consultant, GP or by an HCPC-registered podiatrist, but they’re usually provided by an orthotist. You can also opt to see an orthotist or orthopaedic shoemaker privately. Each NHS hospital trust will have its own arrangements for footwear referral and entitlements.
Many people prefer to wear slippers in the house. However, slippers aren’t a good idea for those who have to wear special insoles. They also sometimes contribute to falls in the elderly. The uppers of slippers are often soft, so they’re comfortable for hammer toes and prominent joints, but the soles may lack adequate cushioning and grip. Like outdoor shoes, slippers should fit properly and shouldn’t be too loose. Backless slippers and slippers with a high heel really should be avoided. The features of the ideal slipper are generally the same as for the ideal shoe.
If you need to wear safety boots for work, they should display the British Kitemark or CE mark. If your existing safety footwear is uncomfortable, you may need to talk to your employer about getting alternatives. Safety versions of extra-depth and cushioned shoes are available. If you suffer from toe or foot ulceration, make sure that safety footwear is not causing pressure or pain to the wounds.
Many slippers, shoes and boots are available with linings such as sheepskin or synthetic fur to help keep the feet warm. Wearing thicker socks or two pairs (as long as they’re not too tight) not only helps to keep the feet warm but also provides extra cushioning under the soles of the feet. Keeping the feet warm will also be easier if you keep the rest of your body warm.The Raynaud’s & Scleroderma Association produces a leaflet containing tips for keeping warm.
An orthotist or podiatrist will be able to advise on special insoles and custom-made or adapted shoes. Rheumatology and general practice nurses are usually able to offer advice and assistance with routine foot care and possibilities for onward referral.
Ankylosing spondylitis – An inflammatory arthritis affecting mainly the joints in the back, which can lead to stiffening of the spine. It can also affect the heels and can be associated with inflammation in tendons and ligaments.
Bursa (plural bursae) – A small pouch of fibrous tissue lined (like a joint) with a synovial membrane. Bursae help to reduce friction; they occur where parts move over one another, e.g. where tendons or ligaments pass over bones. Others, however, form in response to unusual pressure or friction – for example, with a bunion.
Enthesopathy – Pain or discomfort at the point where a tendon or ligament inserts into a bone (the enthesis).
Fascia – Connective tissue that wraps around muscles, blood vessels and nerves to bind them together.
Gout – An inflammatory arthritis caused by a reaction to the formation of urate crystals in the joint. Gout comes and goes in severe flare-ups at first, but if not treated it can eventually lead to joint damage. It often affects the big toe.
Hallux rigid us – Osteoarthritis of the big toe joint with a stiff, often painful, big toe.
Hallux valgus – A condition in which the big toe pushes across towards the other toes, often associated with osteoarthritis of the big toe joint. It’s often referred to as a bunion, although in fact a bunion can exist without hallux valgus.
Inflammation – A normal reaction to injury or infection of living tissues. The flow of blood increases, resulting in heat and redness in the affected tissues, and fluid and cells leak into the tissue, causing swelling.
Ligaments – Tough, fibrous bands anchoring the bones on either side of a joint and holding the joint together. In the spine they’re attached to the vertebrae and restrict spinal movements, therefore giving stability to the back.
Non-steroidal anti -inflammatory drugs (NSAIDs) – A large family of drugs prescribed for different kinds of arthritis that reduce inflammation and control pain, swelling and stiffness. Common examples include ibuprofen, naproxen and diclofenac.
Occupational therapist – A therapist who helps you to get on with your daily activities (e.g. dressing, eating, bathing) by giving practical advice on aids, appliances and altering your technique.
Lupus (systemic lupus erythematosus or SLE) – An autoimmune disease in which the immune system attacks the body’s own tissues. It can affect the skin, the hair and joints and may also affect internal organs. It’s often linked to a condition called antiphospholipid syndrome (APS).
Orthosis (plural orthoses) –A device to help part of the body to work better. An orthosis is used to provide support or to adjust the mechanical function of a joint, for example for the foot or ankle. Most foot orthoses are insoles worn inside the shoe. They may range from very rigid to soft depending on their purpose. Orthoses are also referred to as functional orthoses.
Orthotist - A trained specialist who prescribes and fits orthoses for any part of the body, including insoles and special footwear. Check that your orthotist is HCPC registered.
Osteophyte – An overgrowth of new bone around the edges of osteoarthritic joints.
Physiotherapist – A therapist who helps to keep your joints and muscles moving, helps ease pain and keeps you mobile.
Plantar fasciitis – Pain in the arch of the foot caused by strain to a band of tough fibres that runs from the heel to the base of the toes (the plantar fascia). This term is often wrongly applied to any type of pain in the arch.
Podiatrist – A trained foot specialist. The terms podiatrist and chiropodist mean the same thing, although podiatrist tends to be preferred by the profession. NHS podiatrists and chiropodists are HCPC-registered, having followed a three-year university-based training programme. The podiatrist or chiropodist can diagnose and deal with many of the foot problems caused by arthritis.
Proton-pump inhibitor (PPI) –A drug that acts on an enzyme in the cells of the stomach to reduce the secretion of gastric acid. They’re often prescribed along with non-steroidal anti - inflammatory drugs (NSAIDs) to reduce side-effects from the NSAIDs.
Psoriatic arthritis – An inflammatory arthritis linked to the skin condition psoriasis.
Reactive arthritis – A specific type of inflammatory arthritis that usually occurs after a mild infection.
Rheumatoid arthritis – An inflammatory disease affecting the joints, particularly the lining of the joint. It most commonly starts in the smaller joints in a symmetrical pattern – that is, for example, in both hands or both wrists at once.
Scleroderma – A medical condition characterized by hardening and tightening of the skin. It often affects other parts of the body as well – including the connective tissues that surround the joints, blood vessels and internal organs.
Systemic lupus erythematous –Often simply referred to as lupus, it’s an autoimmune disease which can cause various symptoms in many different parts of the body, including joint pains, skin rashes and extreme tiredness (fatigue).
Tendon – A strong, fibrous band or cord that anchors muscle to bone.
Vasculitis – Inflammation of the walls of blood vessels. This can cause the blood flow to be reduced. Vasculitis can occur on its own (this is called primary vasculitis) or in people who already have an established disease (this is called secondary vasculitis). Secondary vasculitis can happen with a number of different rheumatic diseases, including Sjögren’s syndrome, rheumatoid arthritis and lupus.
