Displaced proximal humerus fracture?

well i'm sure that the MDs at the ER xrayed you ulna/radius and your scapula just to make sure there were no injuries to that part of your arm. are you having muscle spasms? if not then i'm going to assume its not from them, may have pulled a muscle in your forearm. could be having some nerve pain thats traveling down to your lower arm. keep in mind that you did injure your arm and now it's not going to work as perfectly before until it heals
