Information on Removal of Raised Buttocks Scar

Please help with some information on how to remove a scar I got from a fall on my buttocks that is very dark, rough and hideous, also besides the upraised scar there is a sink on the side of the scar, that seems to be destroying my life/self-esteem/ I cannot wear fitted pants because of this/ it is so obvious through the pants a raised lump 2" and a sink under it where the under usually cuts across, help,without the surgical way of cutting or laser? Five years ago I fell off a window sill onto a erect piece of iron, scarring my lower left side buttock cheek, I did not go to the hospital I left the wound to heal on its own, just applied some antibiotic powder. I have a raised scar about 2 inches on my buttocks that is darker than my skin, and beside the ugly keloid, because of the area exactly where the cut of my underwear runs, I have a deformity within the fleshy part around the scar(appears sunken) this is totally wrecking my personal esteem and life.?????
