I read in another thread (the ER one) that you said you have a great primary care physician and 2 lousy neuros.

Therefore, I suggest you call the PCP and tell him where you're at now. Tell, him exactly what you tell us. Make sure to tell him that the Nortriptyline seems to only (very little) help the sensory issues, but not the pain.

ASK him to ADD another drug like Neuronton...and ask that he not start at the bottom of the dosage chart. You are in severe pain and need to get some relief now, not in 3 weeks of slowly increasing the dose. Therefore he should be considering Rxing like 300 mg 3 times a day. That is still a lower dose, but not at the bottom.

Are you getting any sleep?
