When I was child I got hit by a motorcycle on my forehead, and left me with a hematoma bump above my left eye. I am 44 and 2 years ago, a dermatologist surgically removed a piece of fat tissue about 1/3-1/2 inch in size. We though the bump would disappear, but it did not. I still have this small bump, but noticeable. It becomes more noticeable after exercising under the sun, getting agitated, stress, or preoccupied. Could you please give me advice?
