I don't think this is a problem at all… medically or otherwise.
Our self-imposed moratorium against "medical advice" is often overdone — It is really geared towards users requesting or dispensing personalized medical courses of action/treatment where the situation really requires someone trained in diagnosing your situation specifically to dispense the correct, responsible advice.
That's not to say that some article on the Internet should be used to as a replacement for the proper assessment and treatment of a dislocated shoulder… but you were very clear about that.
If you think about it, one might say it's equally ludicrous for people to take their life into their own hands by taking "safe hiking advice" from a site like this. But nobody is suggesting that we shouldn't be allowed to talk about this stuff either.
Posting this information can only make this site better. Whether the subject is medical knowledge or legal situations or whatever, not being qualified or "licensed" in some field doesn't mean I should remain ignorant of the subject altogether. Let's get over these "medical questions" being a trigger point of something we should every discuss in any form. Enjoy.
