Arthritis nodules are firm lumps that develop under the skin, most often in people living with rheumatoid arthritis. They are usually found on pressure points such as the elbows, fingers, and knuckles, but can sometimes appear in other areas of the body.
These nodules form as a result of chronic inflammation in the joints. They can range in size from very small to several centimetres wide and may be painless or tender depending on their location. While they do not always cause discomfort, larger nodules can interfere with mobility or daily activities. Their presence is often a sign of active or advanced arthritis and should be discussed with a healthcare professional.
Causes of arthritis nodules
Arthritis nodules develop when the body’s immune system triggers ongoing inflammation in the joints. This inflammation can lead to the growth of firm tissue under the skin, which becomes visible as nodules.
Several factors can increase the likelihood of developing arthritis nodules:
- Chronic inflammation – persistent joint inflammation in rheumatoid arthritis is the main cause.
- Genetics – certain genetic markers can make someone more prone to developing nodules.
- Joint damage – as arthritis progresses, damage to joints and surrounding tissues can encourage nodule formation.
- Lifestyle factors – smoking and other environmental triggers can worsen inflammation and raise the risk of nodules.
Not everyone with rheumatoid arthritis will develop nodules, but their presence often suggests a more advanced stage of the condition.
Symptoms of arthritis nodules
Arthritis nodules can look and feel different depending on their size, location, and the progression of arthritis. Recognising symptoms early can help with management and treatment.
Common signs include:
- Firm lumps beneath the skin, usually near joints such as fingers, knuckles, and elbows
- Nodules that are painless but sometimes tender if irritated or under pressure
- Sizes ranging from a small pea to several centimetres across
- Nodules that may move slightly under the skin or be fixed to deeper tissue
- Larger nodules that restrict movement or make daily tasks uncomfortable
While many nodules are harmless, painful or growing lumps should always be checked by a doctor.
How are arthritis nodules diagnosed?
Diagnosing arthritis nodules usually starts with a physical examination and medical history. A doctor will check the size, shape, and location of the lumps and ask about arthritis symptoms.
To confirm the diagnosis or rule out other conditions, healthcare professionals may also use:
- Imaging tests such as X-rays, ultrasound, or MRI scans to see whether nodules affect joints or deeper tissues
- Medical history review to understand the type and stage of arthritis and any other health issues
- Biopsy in rare cases, where a small tissue sample is taken to rule out tumours or infection
These steps help doctors decide whether the nodules are harmless, need monitoring, or require treatment.
Treatment options for arthritis nodules
Treatment for arthritis nodules focuses on managing the underlying arthritis and reducing inflammation. Not all nodules require treatment, especially if they are small and painless, but options are available if they cause discomfort or limit movement.
Common approaches include:
- Medication – disease-modifying anti-rheumatic drugs (DMARDs) and biologics can reduce inflammation and shrink nodules.
- Steroid injections – corticosteroids may provide temporary relief for painful or inflamed nodules.
- Surgery – in severe cases, large nodules may be surgically removed if they interfere with mobility or daily life.
- Lifestyle changes – quitting smoking, protecting joints, and reducing pressure on affected areas can help prevent irritation and new nodules from forming.
Most people find that treating the underlying arthritis is the most effective way to control nodule growth and improve comfort.
Supporting someone with arthritis nodules
Caring for a loved one with arthritis nodules can be challenging, especially if the lumps are painful or limit movement. Providing the right support can make a big difference to their comfort and independence.
Ways to support someone include:
- Encouraging them to attend regular medical appointments for monitoring and treatment
- Helping with daily activities that may be difficult, such as cooking, cleaning, or shopping
- Offering emotional support and companionship to reduce frustration or isolation
- Assisting with exercises or mobility aids that protect joints and reduce strain
- Making small changes at home, like providing cushioned supports for pressure points
With patience and understanding, you can help someone manage their symptoms more effectively and improve their quality of life.
