How to Treat Folliculitis?

Dani

(TMI) I have a small spot on the inside of my vulva that looks and feels like a minor burn. From what I've looked up I'm pretty sure it's folliculitis. I just need to know how to treat it because it hurts pretty bad any time it rubs against anything. Obviously i know to wear more loose fitting underwear and such but is there any other way to treat it?
