About 2 years ago I had a nasty cyst grow on my chest. Eventually this cyst was drained of fluid but grew into a big hypertrophic scar. I've since had the scar biopsied, but the scar grew back. Then, I had kenalog injected into the scar which caused a deep depression for 9 months and eventually had the excess kenalog removed until the hypertrophic scar grew back. Should I consider excising the scar or leave it be?
