I'm from Ohio... Have been having PN symptoms for 5 years... been thru a gambit of tests... am currently on Cymbalta, Tramadol, Tramadol ER, Gabapentin, and Nortriptyline. Love my doc as he's up to try anything (within Reason). I'm also making a list of tests that I've had... Hopefully, I can list them and someone... anyone... can give me a few more to suggest.
