Rheumatoid arthritis is a long-term condition that causes pain, swelling and stiffness in the joints. The condition usually affects the hands, feet and wrists. There may be periods where symptoms become worse, known as flare-ups or flares. A flare can be difficult to predict, but with treatment it’s possible to decrease the number of flares and minimise or prevent long-term damage to the joints. Some people with rheumatoid arthritis also experience problems in other parts of the body, or more general symptoms such as tiredness and weight loss.See a GP if you think you have symptoms of rheumatoid arthritis, so they can try to identify the underlying cause. Diagnosing rheumatoid arthritis quickly is important, because early treatment can prevent it getting worse and reduce the risk of joint damage.
