I used to work in an assisted living and there was a new cream called Zostrich. It was way worse than Bengay. I had no idea. I took care of my clients and went off to the Memorial service in the chapel. I sat down next to the Big wig as that was the only place to sit. Had rubbed my eye and obviously had touched my mouth. Sat there for an hour trying to sit still and keep my burning mouth shut, and my eye burning and running down my face the whole time. Feeling like a fool. Of course they dearly departed had been very close to me and then I had to be friendly to the family acting like a nut. I bowed out gracefully as I could explaining it must be an allergy. It took 2 days for the stuff to stop burning. Never used that again without gloves. It can't be washed off.
Ii still hurts just thinking about it.
