Hi, I have not really found any med that helped when I had nerve pain from disc herniations. Percocet, roxicet, ultram, vicodin, vicoprofen ( might have helped a weeeee bit), I cant remember what else i've taken...none really did anything except make me dizzy and such. Luckily, i've always seemed to have success with epidurals and nerve blocks. So far anyway. My most recent heriation actually went away on it's own over 2-3 weeks, thank god!
I have Lyrica right now (though I dont have the nerve pain now), it's making me feel weird....but I might just keep some and save it for the next time I get sciatica and see if it helps.
