Inflammation of the finger joints mostly manifests as joint stiffness, swelling, and pain. In the case of proximal finger joint lesions, the common disease is rheumatoid arthritis. The main symptoms of rheumatoid arthritis of the fingers are: (1) Morning stiffness. There is stiffness in and around the finger joints in the morning after waking up, which lasts more than one hour. (2) Finger joint pain. Pain can occur even when there is no movement. It is often found in the proximal phalanges, symmetrically in the left and right hands, with constant pain and pain when pressed. (3) Swelling of the finger joints. (4) Deformity of the finger joints. The metacarpophalangeal joint may be subluxed, and the fingers may be deflected to the ulnar side. Osteoarthritis of the fingers is mostly without obvious swelling and pressure pain, and initially rarely affects joint activity. The condition must be diagnosed and treated at a regular hospital as soon as possible. If you have finger joint pain, joint stiffness, swelling and other discomfort, please go to a regular hospital in a timely manner, through the physician’s interview and auxiliary tests to clarify the diagnosis, according to the cause of early treatment.
