I hear you, I had a reaction to a sulfa antibiotic and my whole body became a rash, man that was miseryBut you know, itching is painSo you need to take something strong enough at night to let you sleep and not itch, something like vicodanI have had a herpes like rash on my leg a few times, I thought it was a bug bite, I found myself scratching it at night and it got worse and worse.I thought about the stuff on my fingernails not helping it alsoRubbing it just aggravates itSo what I did was take ice out of the fridge and held it there for quite a while, it deadened the nerves and I was able to sleepBut primarily it is a stress induced situation if I hear you rightSo we should pray that God would see you through this situation that brought on this painful rashMay many prayers come your wayand read Mary's post too.
