Shoulder surgery tomorrow 8/21

My shoulders doing ok no pain at all but i'm sure that will change next week when i start doing more extensive rehab,right now just moving it a little and getting some eletro therapy that helps stimulate the muscles.
I'm bored as hell already can't do anything with this sling on and i have to wear it for 4 weeks,makes sleeping interesting.
Woody what did you to your shoulder? I dislocated mine and tore all the ligaments off.
