When I was 12 years old I was hit by a pick up truck that threw me into a large rock. When I was thrown into the rock my outer thigh is what landed directly on it. Ever since that accident I have had a large lump on my outer thigh that you can see my veins through my skin, has no feeling unless it is hit hard (but the feeling is still not normal), and gets larger as I gain weight. I haven't gained that much weight, maybe about 5 lbs, but the bump has grown a noticeable amount. Now I am starting to get stretch marks on just this thigh on the inside and it is becoming more sensitive. Do you have any suggestions on what this could be, or how to get rid of it? When I went to the hospital when I got hit I was told that it was a hematoma and should be gone within six months. Well I will just restate that I was 12 when this injury occurred, and I am now 19.
