Depending on the cause of the hand swelling, you may choose to hang up with the appropriate department in conjunction with your medical history. Common causes include rheumatoid arthritis and trauma. The departments of choice are rheumatology, orthopedics and surgery. 1. If the swelling of the hand is caused by rheumatoid arthritis, choose the Department of Rheumatology and Immunology. 2. If the swelling is caused by osteoarthritis due to trauma, infectious inflammation, etc., orthopedics is the department of choice. 3. If the hand swelling is caused by external force, sprain, contusion, crush injury, etc., local cell destruction, resulting in local tissue congestion and edema, you can consult the Department of Surgery or Orthopedics. If hand swelling persists for a long period of time, it is recommended to go to the hospital in a timely manner and register with the appropriate department according to one’s own medical history, or go to the hospital service desk, consult with the nurse practitioner, and follow the advice of the nurse practitioner to choose the appropriate department.
