Sorry you are in such misery, I was in a simalar situation. What saved me was gentian violet. I covered myself in it, I was very purple for a couple of weeks, but it healed my skin. Some dr.s' say it will permenatly stain you purple, not so. It instantly takes away the pain the infected skins dries up and falls of leaving nice new skin that is not infected. You will be quite a mess for a while(all purple), but it sounds like you are already. I know I was, but this helped save my life. Google it, kills everything in a month or less. Please try, I never thought I would ever recover from such misery, if I can, you can, I'm almost twice your age.
