Rheumatoid arthritis, or RA, is an autoimmune disease that causes your immune system to attack healthy cells in your body. This attack causes inflammation in the parts of your body that are affected.
RA attacks many joints simultaneously and is most common in the hands, wrists, and knees. When a joint is affected by RA, the joints lining becomes inflamed, leading to long-lasting chronic pain, lack of balance, and deformities.
Addressing RA flares as early as possible helps prevent lasting joint damage. If you think you may be in an RA flare, contact your provider as soon as possible.
