Hello.
The doctors says this what I have might be small fiber neuropathy, because the EMG was negative. Mine started almost a year ago. At first the burning sensatio was in my legs Then the intense burning gradually spread to other parts, and is now all over the body with intense burning. I noticed, that after the burning has been intense, the numbness comess, mostly my feet, and wrists, but, believe it or not, my gums. The burning pain gets much worse as the afternoon and night coms on. I will describe the burning as if you have an open sore of a scratch on you skin, and you put salt on it or hydrogen peroxide, it really burns. I take Lyrica 3 times daily, and it helps
Best luck to you.
