What is the cause of numbness and tingling after exercise?
Numbness and tingling in an arm caused by exercise or position is often caused by a brachial plexus outlet syndrome. If the problem becomes more troublesome at rest or worsens, different exercise workouts may help. Eventually it may improve spontaneously or the problem may require examination by a specialist to see if it could respond to physical therapy. Severe symptoms will need assessment to determine if surgery is a requirement.
