Six years ago, I had spinal fusion at l4, l5 and s1. The first two years it felt like I was being burned and a switch taken to my legs. After many doctor visits, the pain clinic advised me that my electircal system was messed up . Now, I am prone to muscle cramps, sciatiaca and neuropathy in both feet that are worse than other days. Now, I have pain that comes and goes in both of my legs.
