Hi there, Wow your story is similar to mine, I have had a burning in the feet, legs and hands since last march going on year soon, and it comes and goes, just like you explain, I have undergone an MRI of spine and they found a herniated disk in c5 c6 and a bulged c4c5 and I also had an MRI of brain and it was normal, and a bunch of blood work and its all normal, I have no idea what can be causing such a bizarre thing to happen and come and go so frequently but when its here its so painful, like acid all over my body~bad burning and a raw feeling like frostbite kinda..real odd stuff!!!
