Hi Pitou - I have tried gabapentin and pregabalin (Lyrica) for nerve pain with many side effects but you might consider trying Botox injections. Maybe you will tolerate it better and the Botox is supposed to stay localized although it didn't for me. You also mentioned Lyme disease and I remember having a blood test completed by an infectious disease specialist and it came back negative so that partially helped determine I had MS. Ask your doctor about it. I wish you all the best.
