Finger arthritis is common in people who work hard on their hands and do a lot of finger flexion and extension. Its treatment methods are the same as osteoarthritis. 1. Keep your hands warm and avoid cold water irritation. 2. Try to avoid repetitive movements of finger joints to reduce joint damage. 3. Drugs such as glucosamine or topical Voltaren can be used for treatment, which can help relieve symptoms such as finger joint pain, swelling, and morning stiffness.
