I have neuropathy caused by the medication Prograf, an anti rejection medication that I take, as I had a lung transplant in 2006. Unfortunately I have extreme burning in my legs and feet, and tolerable burning in my arms, and my face sometimes... the Gabapentin I take does not really help a lot, I take 400mg 3 times a day. Is there something else I could do or take to alleviate this discomfort.
