Rheumatoid arthritis is a long-term condition that causes pain, swelling and stiffness in the joints. Rheumatoid arthritis is an autoimmune disease. This means your immune system – which usually fights infection – attacks the cells that line your joints by mistake, making the joints swollen, stiff and painful.
Over time, this can damage the joint itself, the cartilage and nearby bone. There’s no cure for rheumatoid arthritis. However, early diagnosis and appropriate treatment enables many people with rheumatoid arthritis to have periods of months or even years between flares. This can help them to lead full lives and continue regular employment.
