I injured my shoulder about 3 months ago and I did rehab for it for it massaged its everyday as much as possible and it seemed to get a little better but there was one particular part that would still hurt no matter what I did for it , the would would only happen when i raised my armup to the side and put it in a V with my fist touching my chest. I was going to go to the doctors and have them look at it possibly have an MRI done but my father kept telling me he had the same injury when he was younger and that the pain i might be feeling is just scar tissue that should be broken down by slowly getting back into lifting weights so i tried it i was fully capable of do tri extension a few curls push ups etc and after that my shoulder felt much better its been 3 days the pain is still there but it isnt half as much as it used to be. Does this sound like my my father right or should I go get my shoulder looked at ?
