[|Human|] The past few days I have an unexplained tenderness and small lump on outer side of upper right arm along tri-cep region, tonight I noticed lump appears smaller, not quite as tendery and that there is bruising. I have worn long sleeves past few days and had not actually examined my arm , so the bruising may have been present earlier. Bruising is dark in colour and not symmetrical in shape. There has been no over exertion past week or any trauma. I am 61 yr old female .
[|AI|]  Hi, Dear,Welcome with your query to Chat Doctor. Studied your query in full depth of its details. Reviewed it in context of your health concerns. Based On the facts, You mostly seem to suffer from-It is very difficult and challenging job to opine on the tender lump with bruising of dark color. With My experience at your age, this asymmetrical dark bruise without any obvious history of recent trauma-you seem to have Petechial hemorrhages due to tissue and capillary fragility. Reasons of this tender bruise could be blunt unnoticed trauma with fragile capillaries by age. It seems that you are on blood thinners, which would then explain this tender lump with bruise. If Yes, then maintain proper INR by checking the bleeding and clotting time to be maintain between 2 - 3 INR. Second opinion from Physician specialist would resolve this issue for you.
