So I have length-dependent small fiber poly neuropathy. This is a recent diagnosis. Previously I was treated for fibromyalgia. I took Gabapentin several times over the past seven years, but it made me so drowsy. In researching SFN, I saw an article that referenced Tegretol as a treatment for a particular diagnosis. Coincidentally I had been on Tegretol for 25+ years for seizures. I stopped taking it in 2014, and my pain, weakness, fatigue started within 6 months. For that reason, we are resuming Tegretol. It’s not a first choice for neuropathy because other drugs have fewer side effects.
