My left arm, about two inches about the wrist on the ulna side, got slammed into the side of an open door on Monday a week ago. I do not have insurance and was just able to go the ER. No broken bones were found in the x-rays, but I still have HUGE hematoma that looks like a goose egg at the point of impact. I am bruised from the back of my arm, just above my elbow to the tips of my fingers and the palm side of my hand. How long will it take this hematoma to go down and how do I treat it? The ER referred me to an orthopedic doctor, but I don t have insurance, nor can I afford that.
