Had to have mine done twice, when the surgeon got in there the 2nd time it was a lot worse than he thought. Tendon was shredded, had to implant several anchors in the bone and stretch remaining good tissue up to where it needed to be attached. I had arm and shoulder totally immobilized for 6-8 weeks before doing anything. Surgeon was concerned that I would tear tendon away from where he had it anchored. Told me to follow instructions closely and not over do it, because if I tore it away from the anchors he wouldn't really have much to work with to try again. I was a good patient and did what I was told, was back to full weight bows in about 6 months. And yes that was crazy pain, when I woke up from surgery I would have given anyone nearby a $1000 to put me out of my misery, and I consider myself to have a pretty high threshold for pain, or a least I thought I did. They ramped me up so much on morphine to control the pain I ended up with my respiration tanking and that became a whole other issue. But, after a couple sleepless nights in the recliner I was able to get off the pain killers and managed with just ibuprofen.
