Rheumatoid arthritis is an autoimmune disease that attacks the joints. Although it shares some symptoms with osteoarthritis, the type of arthritis that usually occurs in older people due to wear and tear on joints, there are some key differences. Rheumatoid arthritis can attack at any age, can come on rapidly, and may be accompanied by other symptoms, such as fatigue.
