Rheumatic diseases are relatively complex and there are many types of rheumatism. Which finger is the first to develop rheumatism varies from person to person. When rheumatism attacks, it is not always the fingers that develop, but also the joints that may have symptoms first, so it depends on the specific situation, commonly rheumatoid arthritis, osteoarthritis and gout, etc. 1, rheumatoid arthritis: the first parts of the hand involved are often the joints between the fingers and the palm of the hand, called the metacarpophalangeal joint, and the interphalangeal joint near the metacarpophalangeal area, called the proximal interphalangeal joint. Rheumatoid arthritis attacks easily involved, and is also the earliest onset of the site; 2, osteoarthritis: involvement caused by the lesions are often sclerotic hyperplasia, such as the distal joints of the fingers called distal interphalangeal joints, there is significant local joint swelling; 3, gout: caused by the joint lesions in the finger joints is very rare, mostly seen after repeated attacks of gouty arthritis, gradually involving the fingers. Involved sites include distal interphalangeal joints, proximal interphalangeal joints, metacarpophalangeal joints and wrist joints. In other rheumatic diseases such as tendonitis and tenosynovitis, there is no definite site of involvement, and it is mostly related to the joints with a lot of activities. Therefore, patients with rheumatic diseases may be involved in all parts of the fingers, and the order of onset varies. If you have finger joint discomfort, you should visit the rheumatology department as soon as possible to clarify which rheumatic disease is causing it in order to get effective treatment.
