Since my late 20's, I have seen a variety of dermatologists for painful boil-like eruptions on my butt, that are 1-3 CM in diameter. I am now 39, and they seem to be getting worse! I feel like I'm not getting anywhere. I am currently using a benzoil wash, and in the past have used such topicals as tretinoin (some success), clindomycin, evoclin, desonide, and oral antibiotics; minocyline and now solydyn.
