I was in a bike accident 3 weeks ago which resulted in 20 stitches to face, bruises, contusion, broken teeth, and arm pain. Right now my issue is with arm pain....I have been taking ibprophen and getting no relief. It is a constant dull pain. Using my arm for different things (steering, opening door, lifting things) is painful. Xrays were taken to everything and nothing is broken. What can I do to heal this...
