I recently went over the handle bars and landed on my arm as the bike came flying in the air after me! I was riding with a buddy he was in front of me, it was all technical trails we were riding, going over rocks, logs, bridges, roots, streams. But the crazy thing was where i went down at was a wide trail and nothing in the way until this hidden tree was covered with weeds and my pedal hit it and i went flying off.. Now its been 4 days only, i have a stiff arm its like my bicep muscle. I went to the doctor he thinks i have a ripped my rotater cuff, but i do not have sharp pain, i think i just need some rest. Has anyone had this happen to them?
