I had a serious shoulder injury myself, although I did not have surgery as I opted not to due to the unasured outcome. I will say its been a long road back to being 100% and I'm still not there yet. Its been over a year and my strength is not back to what it was pre-injury. My advice would be to get a second opinion, and take it very very slow in your return to the weight room.
