The most common symptoms of juvenile arthritis are pain, tenderness and stiffness of the joints resulting to a limited range of motion.

Another common symptom is joint contracture which is a result of holding an affected joint in a flexed position for prolonged periods.

In some cases, the bone or joint cartilage becomes damaged which leads to joint deformity and/or impairment of joint use. Altered growth of joints and bone can also occur which leads to a short stature.

The symptoms usually differs from one case to another depending on the severity of the condition and the affected areas.
