I actually tripped and fell on 10-10-09 and tried to use my arm on the couch to stop the fall (didn't work) and ended up with a extremely large bruise on my left upper arm and left knee and lower leg. The pain with certain movement did not begin until a couple of weeks after this incident. I am curious if I could have injured my rotator cuff when I fell and would like to get a little more indepth ansmwer. I am scheduled to see an ortho specialist but would like to get a "information only" response. Thank you very much.
