hey im 17, recently got out of a cast from breaking my left arm( the bones were ulna and radius) from a kick to the arm while at school. well after getting out of the cast i noticed a lump on my arm and the doctor said itd be fine but im still concerned, is it possible that it is a calcium build up. and if it is a calcium build up will it go back to normal eventually here are some pictures
