Need exam: Typically you should not have numbness in your shoulder this far out after surgery unless you had it prior to surgery. You need to be examined. It could be related to other causes such as a disk in your neck or medical issues. See your doctor and good luck.

Nerve issue: Your numbness can be due to abnormal nerve function due to nerve impingement or damage. Treatment varies depending on the cause of the problem. Have it evaluated and appropriately treated.
