You're giving oodles of wrong information in this thread. I'll only address some of it. First, your shoulder does not have to be "hanging like a noodle" to be completely fucked. Yeah, dislocations have a tendency to cause serious shoulder problems, but some people can pop their shoulder once, and never have it happen again. I tore my labrum four years ago, and before surgery, popped my shoulder out at least every day. I even popped it out from sneezing too hard on several embarrassing occasions. I got surgery after about 5 months of physio, and about six months after the initial skiing-related injury. This leads me to my next argument: surgery helps a hell of a lot more than it hurts. My shoulder is no where near fixed, despite my doctor guaranteeing a 98% success rate, but I no longer have to worry about dislocating it while washing my hair or other easy shit like that. Now my third point: depending on what part of the shoulder is injured, it doesn't have to "ache like there's no tomorrow!!" to know that it's fucked. When my injury happened (1st dislocation), I was only in severe pain for about a day. I wore a sling for a few days after (as my doctor had prescribed) and after a week I was cleared for all physical activities. My shoulder felt tight and strong. I then played some volleyball, went for a jump serve, and my shoulder came out right quick. This (1 day of pain then no pain at all after a dislocation) continued, and my shoulder came out more and more. Overall, please realize that there are a shit ton of injuries that can happen to a shoulder, and don't assume that since you were so lucky with yours, everyone will be with theirs. Don't post shit if you don't know what you are talking about.
To the OP: Since getting your shoulder checked out isn't an option, just take it real easy for a week or two. Then do some small shoulder exercises, using extremely low weight and high reps. Just google "shoulder rehab exercises" and you should find tons of useful stuff. Whipper is completely wrong when he says that physio doesn't help. If you do it correctly and promptly it will build the muscles up around your shoulder, hopefully tightening it up enough that you won't have any more issues. I hope you get all healed up; shoulder injuries SUCK.
