Rheumatoid Arthritis is an autoimmune inflammatory disease causing pain, swelling, stiffness and loss of function in joints. The immune system attacks tissues lining joints which over time cause damage to bones and cartilage, weakening the muscles and tendons that support joints.
It is estimated that about 1.3 million people suffer from Rheumatoid Arthritis. This is a disease that mainly affects women and usually begins in middle age. Symptoms of Rheumatoid Arthritis include fatigue, weakness, fever and pain/stiffness or swollen joints.
