Rheumatoid arthritis is traditionally considered a chronic, inflammatory autoimmune disorder that causes the immune system to attack the joints. It is a disabling and painful inflammatory condition, which can lead to substantial loss of mobility due to pain and joint destruction. The disease is also systemic in that it often also affects many extra-articular tissues throughout the body including the skin, blood vessels, heart, lungs, and muscles.

Daily joint pain is one of the most common symptoms for rheumatoid arthritis. Most patients also experience some degree of depression, anxiety, and feelings of helplessness. Some of the more common symptoms for rheumatoid arthritis include: morning stiffness in and around the joints, at least three joint areas with simultaneous soft tissue swelling or fluid, and at least one swollen joint area, in the wrist, knuckle, or middle joint of the finger. The disease often affects the wrist and finger joints closest to the hand.
