Suggest Remedy For Redness And Burning Sensation In Vagina

My bottom, inside of my legs, and under my abdomen looks like a raw piece of meat! It feels like someone has scalded me. I have taken two rounds of Bactrim for Folliculitis, but it has not helped with the redness, and burning. What can I put on this to make it go away? I have used antibiotic sauve, anti-itch cream with cortisone, and preparation H cream, and soaked in Epsom Salts baths.
