手部因类风湿性关节炎引起的炎症

oid arthritis (RA) commonly causes inflammation in the hands, leading to pain, swelling, and stiffness in the joints, particularly the small joints of the fingers and wrists. This inflammation results from the immune system attacking the body's own joint tissues, causing the synovium (lining of the joint) to become inflamed and release chemicals that damage nearby tissues.
