Well I think the one thing you need to keep in mind is that everyone is a bit different and a lot will depend on what needs to be done.
I had a SLAP repair done this past Friday plus I think a repair for bursitis, I did not see my doctor after surgery and he was in surgery today when I was in the office to get the dressing changed on the incisions. I did have an MRI with the contrast but my doctor told me in my preop that the MRI does not always show the real story things could be better or worse, your doctor will not know all the details until he does the scope.
I have read a lot of experiences on this site as well prior to surgery some good and some not so good. They really helped me to mentally prepare for the surgery. And I really really wish the best for those that are having a difficult time with there recovery.
My doctor had me moving the shoulder day of surgery, I can now move it up about half way to shoulder hight with minimal pain. Don't get me wrong I have let out some screams from pain when I moved it first 2 days but each time it gets a little less painful.
I must say that I had a fair amount of anxiety for the surgery, and in recovery I was told that going into surgery I told my doctor that I changed my mind I don't want the surgery

, don't remember telling him that.
From what I have been told and have researched, if you have a SLAP tear surgery is the only real option to fix it. But if you have questions you may want to talk to your doctor and get the MRI with the contrast, it may help to easy you mind.
