I have had the burning in my buttock and feet since I had back surgery approx. 7 yrs. ago. I have been to many doctors and clinics to no success. Ice does help and then I take percocet with gabapentin . I always get up each morning and run cold water over my feet or soak them in cold water. That does seem to help too. When this doesn't help I'm am in tears. Very hard to sit.
