postherpetic neuralgia
"I have had PHN for 2 years and have been in extreme pain.  My Internist told me about Zostrix HP along with the warning to be careful applying it and to wash it off my hands.  I started using latex gloves to administer it on my body and after 2 weeks my pain began to subside.  I am now at a very manageable pain level.  On a 1-10 with 10 being the highest pain I am now finally at 0.5 (point five) after 2 years of being at a pain level of 10 day and night.  I use it sparingly (pea sized amount) 3-4 x a day.  I highly recommend it if you had shingles and then PHN."
