Rheumatoid Arthritis: Exercise, Flare-Ups and Physiotherapy

Rheumatoid arthritis can make exercise feel confusing. Movement may help with stiffness, strength and confidence, yet an inflamed joint can become warm, swollen and painful during a flare. The answer is usually not to stop moving altogether, but to adjust the type and dose of activity while your medical treatment controls the disease.

This guide explains how exercise and physiotherapy can support adults with rheumatoid arthritis, how to adapt during a flare, what progress may realistically look like, and when symptoms need medical attention.

What is rheumatoid arthritis?

Rheumatoid arthritis (RA) is a long-term autoimmune condition. The immune system mistakenly attacks the lining of joints, causing inflammation, pain, swelling and stiffness. It often affects the small joints of the hands, wrists and feet, frequently on both sides, but it can affect other joints and wider health too.

RA is different from osteoarthritis, although a person can have both. Osteoarthritis is mainly associated with changes in the joint over time, whereas rheumatoid arthritis is an inflammatory autoimmune disease that normally requires specialist medical treatment. You can read our separate guide to knee osteoarthritis and exercise.

Physiotherapy does not replace disease-modifying anti-rheumatic drugs (DMARDs), biological medicines or rheumatology care. NICE recommends a treat-to-target approach that aims for remission or low disease activity. Exercise works alongside that medical plan.

Can you exercise with rheumatoid arthritis?

For most people, yes. Regular, appropriately dosed activity can help maintain joint movement, strengthen the muscles that support the joints, improve general fitness and make everyday tasks easier. The NHS recommends building exercise gradually and balancing activity with rest.

Useful options may include:

• Mobility exercises to move affected joints gently through a comfortable range.
• Strength work using body weight, light resistance bands, weights or functional tasks such as controlled sit-to-stands.
• Low-impact aerobic activity such as walking, cycling, swimming or aqua aerobics.
• Balance exercises if pain, weakness or reduced confidence has affected steadiness.
• Tailored hand exercises when pain or reduced function affects the hands or wrists.

There is no single best programme for everyone. The right starting point depends on which joints are affected, current disease activity, fatigue, medication, other health conditions and what you need to do at home or work.

How should exercise change during a flare?

A flare is a period when symptoms become noticeably worse. Joints may be more painful, hot or swollen, and fatigue can increase. A flare does not automatically mean complete bed rest, but it is sensible to reduce the load on actively inflamed joints.

During a flare, you might:

• reduce resistance, repetitions, impact or exercise duration;
• use short, gentle range-of-movement sessions rather than forcing a painful stretch;
• switch from a painful activity to a lower-impact alternative;
• spread essential tasks across the day and use planned rest periods;
• avoid repeatedly loading a joint that is becoming hotter, more swollen or severely painful;
• contact your rheumatology team if the flare is significant, persistent or not responding to your agreed plan.

NICE says adults with RA should have rapid access to specialist care for flares and know how to contact that service. Do not change or stop prescribed medication without advice from the clinician managing it.

How hard should you work?

Use symptoms as feedback rather than treating every ache as damage. Mild muscular effort or temporary stiffness can occur when you start or progress exercise. However, severe pain, marked swelling or a joint becoming hot after an activity suggests that the dose may be too high.

A practical approach is to change one variable at a time: add a few minutes, a small amount of resistance or one extra set, then observe how you respond later that day and the following morning. If symptoms settle back towards their usual level, the change may be manageable. If they remain clearly worse, reduce the dose and seek advice if you are unsure.

How can physiotherapy help?

A physiotherapist can assess movement, strength, function and the demands of your daily activities. The aim is not to “cure” rheumatoid arthritis through exercise, but to help you remain active and independent while working alongside rheumatology treatment.

Depending on your needs, physiotherapy may include:

• a graded mobility, strength and cardiovascular programme;
• ways to adapt exercise during flares without losing all activity;
• hand and wrist exercises when appropriate;
• pacing strategies for pain and fatigue;
• advice on returning to work, hobbies, walking or the gym;
• monitoring how joints respond and communicating concerns back to the medical team.

Online physiotherapy can be useful for observing movement, discussing symptom patterns, progressing home exercise and adapting everyday tasks. It cannot provide blood tests, imaging or a medical diagnosis of RA, and it should not delay an urgent rheumatology assessment.

What is a realistic recovery timeline?

Rheumatoid arthritis is a long-term condition, so “recovery” is better thought of as controlling disease activity and improving function rather than following a fixed healing deadline. Medical treatment may need review and adjustment over time. Exercise progress is also individual.

Some people notice that gentle movement reduces stiffness during or shortly after a session. Meaningful improvements in strength, fitness and confidence usually require consistent work over weeks to months. Flares may temporarily interrupt progress, but a planned reduction followed by a gradual return is not the same as starting again from zero.

Success may mean walking farther, opening jars more comfortably, managing stairs, returning to a valued activity or feeling more confident about what is safe. Your plan should reflect goals that matter to you.

When should you seek medical help?

Arrange a GP assessment if you have unexplained joint pain, swelling or stiffness that does not settle within a few days, particularly if several joints or the small joints of the hands or feet are involved. NICE advises urgent specialist referral for suspected persistent synovitis in these circumstances; normal inflammatory blood results or negative antibodies should not be used to delay referral.

Seek urgent help from NHS 111 or an urgent GP service if you develop severe pain and swelling in one joint that starts suddenly, a red or hot joint, or joint pain with a high or low temperature, shivering or feeling acutely unwell. These features can indicate infection or another condition that needs prompt assessment.

Also contact your rheumatology team promptly if a known flare is severe, keeps worsening or is not responding to your agreed management plan. New eye symptoms, chest symptoms, unusual breathlessness or neurological symptoms should be medically assessed rather than assumed to be a musculoskeletal flare.
