During treatment, my husband took Atarax and used Triamcinolone ointment for the rash. His doc also suggested
Eucerin cream and
Eucerin body wash, to keep the skin moisturized. We used tea tree oil on the few blisters that formed. Sometimes he put ice on areas that were really bothering him, or stood outside without a shirt on at night. Sometimes it was not just the stinging, itching, and redness of the rash, but also the tingling, twitching/jumping/crawling skin feeling that bothered him.
