Many months ago, I had a pain in my upper left shoulder blade and it appeared to be a bruise. I let the bruise go and it has been on back for months now. It becomes itchy randomly throughout the day, and sometimes doesn't bother me. There is no pain associated with it, just discoloration, and itchy symptoms. I do workout on a regular basis, and am not sure if this is causing a reoccurring bruise, but I haven't had pain in that area since the initial bruise. Could this be a hematoma? Or a type of skin cancer? I have attached a picture.
Thank you for your time.
