postherpetic neuralgia
"I've had moderate to severe low back pain for over 20 years due to herniated discs. After years of being handed Percocet (which only worked about an hour for me) and everything up to straight OxyContin, I think I have found something that works!  It's only been about a month, but in combination with Percocet, the severe pain has been minimized. I gave it an 8 because I never want to over hype a medication and I've only been on this about a month."
