What causes arm bruising?
Patient: I have a bruise on my arm that has popped up a few times. It is in the same spot and has the same shape to it every time. I know I didn t hit my arm on anything or pinch it or anything either. The bruise doesn t hurt and if it is the same as the other times and will have it for about a month which is much longer than normal bruises that I know how I got. What could be the reason for this?? Doctor: Hello,Bruises without any cause can be related to bleeding disorders. I suggest to do a complete blood count and platelets level for further evaluation.Hope I have answered your question. Let me know if I can assist you further.  Regards, Dr. Dorina Gurabardhi, General & Family Physician
