Iv had a repair done for a SLAP Lesion and a Bankart Lesion. It wasn't really that bad except for the some days where the throbbing pain would not stop. I didn't use many painkillers since they really had no effect, and for some reason they would keep me up at night and was unable to sleep.
If they offer a nerve block. THAT IS A MUST! Sure your arm will be paralyzed for a long time and you won't feel the real pain, makes sleeping it off a lot easier. I also had 9 anchors inserted into my shoulder.
The anesthesia wasn't too bad, just rolled my oats once, after i stomached it so I could get released early. All I remember before I went under was it felt like my veins are on fire, followed by this feeling is the best!!, followed by I'm sleepy.
Also... i forgot PHYSICAL THERAPY!!! AND STICK TO IT!!!
