[|Human|] Hi, I have a lump about 1/2 in diameter on the inside of my forearm surrounded by a fairly dark bruise. I don t recall bumping or straining my arm to cause this internal bleeding and there is only a slight soreness. I don t bruise easily. Should my doctor?
[|AI|]  Hello and welcome to Chat Doctor, A lump on the forearm surrounded by dark bruise suggests a hematoma formation probably after trauma or injury. Is there any history of trauma to the site? If yes, then the trauma is responsible for the lump and bruising. The hematoma will disappear and bruising will also disappear with time. In case there is no history of trauma then probably there is some other reason for the bruising. In that case you will have to consult for primary healthcare provider. Thanks and take care Chat Doctor.
