What can I do for bad pain that never stops from post herpetic neuropathy. I could not take gabapentin or lyric?

Many options. Gabapentin (neurontin) and Pregabalin (lyrica) are appropriate, but there are many others, including cymbalta, (duloxetine) Amitriptyline (elavil), topical capsaicin (zostrix), Lidocaine patches (lidoderm), Carbamazepine (tegretol), and even b vitamin supplements, and others. A neurologist, physiatrist, or pain specialist can help select the right drug or drug combination for you.
Yes those two . Medications are appropriate options. I prefer lyrica (pregabalin).
