This condition primarily arises from trauma caused by external forces, such as soft tissue injury of the hand or swelling due to bleeding after a fracture. Even without external injury, conditions like gout or infections may lead to rheumatoid arthritis, stenosing tenosynovitis, and other causes of aseptic inflammation in the hand, resulting in joint pain and swelling. It is important to keep warm and protect against cold; generally, one should maintain good health, ensure proper indoor ventilation, and prevent pathogen exposure.
