dermatitis
"At the start of every summer for 5 years my son gets the worst mystery rash on his back (Contact Dermatitis) they call it. We just can't figure out what that contact is. It has itched so badly in the past that he had actually scratched himself bloody and had to be sedated at the ER.  Finally his doctor prescribed Lidex 0.05% and almost instant relief. It's been amazing. No side affects to date for him. I don't know who created it but Thank you."
