Has anyone with this disease tried Tea Tree Oil? It is anti-fungal, bacterial, viral, parasitic, etc. It cleared my ring worm right up and my father used it to kill a staph infection. It also kills lice and scabies. Used with a carrier oil (like coconut) it has some skin penetration. You can't use it straight as it will burn you. It must be at least 50/50 with a carrier oil, probably even less on the face.
If it were me, I'd get a big old jug of oil and lube it up every night. Wash up in the morning.
