I am looking for recommendations for my wife's postherpetic neuralgia on her back. We recently relocated to the mid-south to be near our grandchildren. My wife has suffered terribly for nearly four years. Her medications (gabapentin, Lyrica, and various creams/ointments, opiates) have had nasty side effects and/or provided no relief. Would someone recommend a treatment or a good physician in the mid-south? Thank you.
