i responded about my rotator cuff injury in this thread a few days ago (think i've got frozen shoulder) and my ins. paid for p.t.; however, if p.t. is not an option and you are a member of a gym or can buy some of the bands, the point i am trying to make is if you go to youtube there are a large no. of videos for doing p.t. for your particular injury which essentially is the shoulder, back, biceps/triceps area; i found some videos that i use every morning and when i saw ortho. a few days ago, there was noticeable improvement...at least no pain when sleeping in any position and i can now lift heavier weights...i had p.t. for a month before i was able to see the ortho. and i found videos even before getting the ortho. diagnosis...and when i saw ortho 1st time, he showed me only 2 exercises when he diagnosed frozen shoulder w/o an mri, and i came home and found so many youtube videos for frozen shoulder. i did get a cortisone injection but you can't get too many of them but the p.t. definitely is the way to go and everyone i know refuses surgery for whataver rotator cuff injuries they are dealing with, but my friends are old like me (i'm 71) so if you're young, maybe surgery is the answer....
