Hi EC, the mri showed an inflamed supraspinatus, no tear. I tried the cortisone and pt for 18 months and nothing seemed to work. I think the surgery certainly made more space for the tendon because after rehab and now that I am playing again I definitely am not getting that catching "impingement" feeling. Somebody on this forum pointed out to me that some people just don't have enough space for the tendons to move around freely.
Certainly it is a lot of committment to complete the rehab and be patient while everything heals. That is why I definitely wouldn't recommend it unless all other options were tried first.
