How do I get rid of scars on my butt? (Photo)

two years ago i had an incident where getting my nails done at a nail salon resulted in a fungus growing under them.the fungus grew on to my torso and though its gone i still have the scars on my butt.how do i get rid of them?i went to my rap around doctor and they suggested going to a dermatologist but all the ones in my area are backed up and seeing the scar has really weighted on me these past few months.ive even considered getting anal bleaching cream and just using it on the area instead
