Had bad fall on soapy slick shower base, fell on mid-humerus & that is where pain is, ex-ray showed no fracture or dislocation. This was 2 wks ago, bruises better, but still pain. Son insists it could be dislocated. ER Dr. said bruising could be a month. I cannot lift arm over shoulder due to pain at this time. Think will subside when bruising leaves, right or wrong?
