Rheumatoid Arthritis: Overview
Rheumatoid arthritis (RA) is a disease that causes joint pain and swelling. It primarily involves swelling, or inflammation, of the lining of the joints but can also involve internal organs such as the eyes, lungs and heart.
Rheumatoid arthritis is a chronic disease, which means it lasts a long time. Many people with RA note that their arthritis symptoms change over time. At times, people with RA will notice their disease is more active and at others they will notice their disease is less active. Early diagnosis and treatment is essential for the prevention of many of the complications of RA.
