Oh, that brings back memories! NOTHING relieves bone-deep nerve pain. I would lie on the cool tile of the kitchen floor and whimper. Four months to go through the various stages. The blisters look spectacular but they actually didn't hurt - mine went away after a couple of weeks. My doc said I had immunity for a year afterwards, then advised Shingrix. 300.00 for two shots but well worth it. No coverage public or private insurance where I live.
