I am taking 600 mg Neurontin three times a day and 60 mg Nortriptyline with no side effects. Has my pain pretty much under control.

Do you know the cause of your small fiber neuropathy. I have been tested for all normal causes. I still feel that until I can treat the underlying cause, the drugs like Neurontin and Nortriptyline just blunt the pain, so it is hard to know if the condition is getting better or worse or still the same.
