Rheumatoid Arthritis Flare Up: What to Know

Symptoms may build gradually or become noticeable over a short time. Hands, wrists, feet, knees, or other joints can feel warmer, tender, swollen, or difficult to move. Morning stiffness may last longer than usual, and ordinary tasks such as opening a jar or walking may take more effort. A flare can affect energy as well as joints; feeling unusually tired is worth recording alongside pain.

A flare does not always affect the same joints each time. Keeping a simple record of the areas involved, stiffness, sleep, fever, recent illness, and medicines can help a clinician distinguish active inflammation from an injury or another problem.

Reduce activities that clearly worsen pain, but avoid keeping a swollen joint completely still for long periods. Gentle range-of-motion movements, comfortable rest, and a cool pack wrapped in cloth may help some people. Keep taking prescribed rheumatoid arthritis treatment unless your clinician has told you otherwise; do not start, stop, or change medicine without advice. A clinician may review disease control and discuss [Anti-Inflammatory Medication](/treatments/non-surgical-orthopedics/anti-inflammatory-medication/).

Contact your rheumatology or primary-care team if the flare is not settling, keeps returning, or makes daily tasks difficult. Bring your symptom record and a list of all medicines, including non-prescription products.

Seek urgent medical help for a suddenly very hot, swollen, and intensely painful joint, especially with fever or feeling unwell, because infection can resemble an inflammatory flare. Get emergency help for chest pressure, severe breathlessness, fainting, new weakness, or trouble speaking. These symptoms need prompt assessment rather than home flare management.

Ask which symptoms should trigger a same-day call, whether your current treatment plan needs review, and which movement or rest pattern is suitable for the joints affected. You can also ask how to track flares and whether another condition, infection, or medicine could be contributing.
