ReefFreak, I had the exact same thing happen to me about 2yrs ago. My joints were always loose; I was a gymnast when I was younger and fully luxated both shoulders at one time or another, so both of the joint capsules were stretched. One day I bumped into something the wrong way and the outer labrum of my left shoulder tore wide open and my arm was hanging out of the socket for a while. Surgery was the only way to repair it; physical therapy is great for strains and pulls, but it can't help with tearing.
And yes, shoulder surgery is some of the most painful. My surgeon was EXCELLENT and talked me through the whole thing beforehand so I didn't have any suprises. You should call your surgeon and have someone explain exactly what they did and what to expect from here on out. There will be a lot of popping and creaking when u start moving around, which won't be for 2weeks at LEAST, so don't be alarmed. Are you in a sling yet, or do you have to go back for a fitting?
The sling they'll give you should have a huge pillow underneath it, so your arm will be held slightly away from your body. It's a pain in the pooper, and your muscles will all atrophy by the time you're allowed to go to physical therapy, so you won't even be able to lift it up high enough to wash your armpit in the shower.
THE most important thin you can POSSIBLY do at this point is rest, eat right, and make sure you get a great physical therapy group.
It's aweful, but it's not th end of the world.
Good luck, man. I hope you feel better! :cheer:
