Ah, yes, the dreaded surgery. I broke the outside of my shoulder (clavicle) last year and luckily every doctor I called downright refused to do surgery. At the time I was very angry and thought surgery was the best thing to do because of the pain involved - Now, nearly 9 months later I do have quite a huge "bump" on my shoulder where the bone pops through but I have full range of motion. I constantly hear/read horror stories about shoulder surgery which leave you only needing more surgery in the future. I'm sure as an old man I will be aching but at 22 I am happy with not going the surgery route.
I hope your injury gets a chance to really heal in the next few months - never forget that the body has been mending bones naturally for thousands of years! Good luck. PS- Sue the first doctor for not giving you full information
