Why does my right shoulder make a popping noise when i raise it above my head? right shoulder blade also tingles at times. no pain just more annoying.

Instability : There are a number of possible causes, but the most common cause of a person to feel popping when raising there arm over their head is some degree of shoulder instability. This may be the result of an injury to the shoulder or can be simply from a generalized ligamentois laxity known as multi-directional instability. Treatment options vary based upon the severity of the problem. Thank you.
