Rheumatoid Arthritis

Rheumatoid arthritis, often called RA, is a long-lasting condition that causes joints to become swollen, stiff, and sore. It happens when the body’s immune system—which normally fights germs—mistakenly attacks the lining of the joints. This is different from the “wear and tear” arthritis that comes with aging. RA can affect people of many ages and often involves joints on both sides of the body.

Common signs include painful, swollen joints, especially in the hands, wrists, and feet. Many people feel stiff in the morning or after resting. RA can also cause tiredness, mild fevers, and a general feeling of being unwell. Because it is an immune condition, it can sometimes affect other parts of the body too.
