Juvenile rheumatoid arthritis, also known as juvenile idiopathic arthritis, is the most common type of arthritis in children under the age of 17. Juvenile rheumatoid arthritis causes persistent joint pain, swelling and stiffness. Some children may experience symptoms for only a few months, while others have symptoms for the rest of their lives.
Some types of juvenile rheumatoid arthritis can cause serious complications, such as growth problems and eye inflammation. Treatment of juvenile rheumatoid arthritis focuses on controlling pain, improving function and preventing joint damage.
