Is this due to weight lifters shoulder? Also called osteolysis? If so I did it just before thanksgiving due to the cavity being closed. I had 5-6mm of bone removed, started feeling great one week after surgery. Started PT abd noticed swelling in the surgery sites. I'm writing this from the hospital as 2 rounds of of antibiotics was not sufficient to get rid of the infection. The infection was painful as hell as well. The surgery was easy, the block was weird, first I had, but saved a ton of pain. I went through this surgery without the block, yeah, it sucks, but they are doing well with pain management.
It's an easy procedure, good luck!
