I have been prescribed Neurontin (Gabapentin) by my Neurologist for Large Fiber Neuropathy. After doing some research on the the drug, I find that the reactions are very similar to the that of Lyrica. I am having back pain, tingling, a feeling that my lips and finger nail areas are cracking and have a headache most of the time. I am wondering if taking this drug and the having the reactions is worth the minimal help it is giving me.... Anyone have this problem that can help???
