Rheumatoid

Rheumatoid arthritis is a chronic inflammatory disease that most often affects the joints, although it can also affect other parts of the body. The cause of rheumatoid arthritis is unknown, but it is believed to be an autoimmune disease, in which the body’s immune system attacks its own tissues. Symptoms of rheumatoid arthritis include joint pain, swelling, and stiffness, as well as fatigue, fever, and weight loss.
