@jakedduck1, Hi Jake. I had my shoulder surgery in about 1992 and not aware of what type it was. My surgery was part of a Shoulder Surgery teaching situation, done by one of the top Orthos of the day, through the University of Calgary in Canada. I even have a tape of the surgery. (Macabre curiosity of an artist. Lol) The surgeon told me afterward that there was even a small bone missing, having been ground away by activity/pressure, etc. I was shifting large (5'x7' etc.) canvases around in my studio, painting on them, etc, which caused that much stress on my joint. ( I'm 5'2" and was 110 lbs). I was in terrific pain for over a year, prior to surgery. I'm sure you're very familiar with shoulder pain, having had 3 surgeries! Ouchie! I was supposed to have surgery on my other shoulder but passed.
PS, I just read @feisty's post. My surgery was Rotator Cuff!
