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 .
