Time to see an Orthopedic MD...don't put it off long. If it's your rotator cuff, depending on the degree of tear, they need to be repaired sooner than later.
Have u seen a chiropractor?
Waiting for the health insurance to kick in next week. Didn't know which way to go, if i should see my gp or just head to specialist. brother tore his to his pieces also. hurts real bad when i try to sleep. can't find a comfortable postion at all.
I had this problem and it was c5c6 cervical spine
Disc blown. After surgery 2 years later I still can't raise arm above shoulder. They tell me it's nerve damage.
Good luck
