I fell on my arm, elbow side down, about a week ago now. It hurt when it happened and has hurt ever since, but less and less. It never bruised. Swelled only a little bit and I can t straighten it out all the way without it hurting (I can almost get it all the way straight now after a week) But there s a lump, not right on the elbow but more towards the underside, and its hard around the underside of the elbow and it goes up the underside of my arm towards the armpit a little. It hurts when touched and when I put pressure on it. Is there anything I should do or could do? And do you think its anything I should be worried about and get it checked out? Could it be something with my nerve? Or a torn tendon? Please help, Thank you.
