Nortriptyline
"I have been taking this for Idiopathic Small Fiber Sensory Neuropathy. Experienced chronic nerve and muscle pain shortly after a flu-like illness. Was diagnosed with late state neurological Lyme Disease by a naturopathic doctor. Neurologist disagreed and diagnosed me with idiopathic small fiber sensory neuropathy. After several MRIs, blood tests, antibiotics, muscle relaxers, gabapentin, a nerve conduction study, a spinal tap, acupuncture and massage therapy sessions, this medicine has helped the most and with the least amount of side effects. Started at 10mg and slowly increased to 60mg over a six week period. At 60mg into my eighth week, I sometimes feel underlying neuropathy. But I can function nearly as well as before the onset of all these problems. So far, so good."
