Last night I noticed a large appearance of what seemed to be a bruise. However, I have had no injury to my arm. This appearance occurred in less than two hours while running to the bank. I am attaching pictures of it, but I assure you that the surface is smooth with no lumps or swelling at all. There is no pain in this area of my arm either. I have not been ill besides the chill from the weather cooling and a slight cough which has been gone for a week now. What could be the causes for this? Should I be concerned? Thanks Ms. Delin P.

Hello, It could be a small hematoma. It could be related to a trauma during running. Anyway, if you have any other spontaneous bruising like this, I would recommend checking coagulation tests and some other blood lab tests (complete blood count, kidney and liver function tests). Hope I have answered your query. Let me know if I can assist you further.
