Just to put an close to this tread.
First of all, I want to thank everyone for their replies agian.
It's been exactly three weeks since my injruy. And I just saw my doctor. They looked at my X-rays and said, the seperation is still a bad seperation and were considering sugery. And then they did some mobility test, and they were shocked at how normal my movement was now. They basically told me I don't need sugery, I don't need to start physio, and I can go back to anything could do before my injury (but just take it a bit easy). I was told it I basically almost fully healed.
So I am no doctor. But I will just let you guys know what I did to make the healing process faster. For the first week, I was in my slig and I iced it like crazy, and took it easy. Week 2-3 I was out of the sling and I alternated it between icing and heating. I also did excercises of rising my arms to the front and side. I ate any thing with vitamen C, cause its suppose to help with soft tissue rebuilding. Also I am only 22 years old, which might have also spead of the healing process.
Looks like I am going to hit the slopes this weekend!
