The story when me being to tired lead to my injured shoulder:this was in 2011,when no one was in bed,I thought that I had the whole bed to myself.I was in uncomfortable positions,so I kept moving alot in bed intill I was at the edge,I fell and blacked out.The next day,I tried to get up but my left shoulder hurt too much,so I couldn't play because my left shoulder,so I had to play mostly on a flat surface where I could move my left shoulder.But I got though it.
