Thought this would be appropriate here.
Injured my shoulder about ten days ago training, was pretty sure I just strained part of my AC Joint that I have chronic issues with since an injury in 2003.
It was not healing and hurting pretty bad still so I get an X-ray Rec from the ER I work in and WTF!! I have a fracture.
Looks like I pulled a tendon so hard instead of tearing it pulled a piece of the bone off with it on the top of my Humerous.
I remember lifting the DB and when I got to the top I felt a harsh sharp pain and then stopped after the third rep thinking this is not right.
Get a CT Scan on Monday.
