How to reduce the pain in wrists and elbow joints. there is a constant itch to snap the wrist or twitch it. how to alleviate this?

Common: This is a common concern from people with mild arthritis, tendonitis, bursitis, etc. Typically it can be helped with strengthening the muscles around those joints, and continued activity. A short course of physical therapy may serve you well to teach you some exercises. For swelling, redness, warmth, or increasing pain....See your dr to rule-out more serious problems.
