I just wanted to say i have the same exact symptoms you have. I've been to so many doctors that i've lost count. The burning is excruciating and nonstop. I've taken so many different drugs also. Including Lyrica and gabapentin among others. I finally came across a neurologist that had seen this before. He told me it was due to a stomach virus i had the week before it occured. The virus had damaged a nerve in the body and he told me that the nerve could not be found and even if it did it could not be repaired. I really don't know if his diagnosis is correct but there is one thing i DO know. He put me on a drug called lamotrigine. It's originally designed for epileptic patients. But its off label use is for nerve damage. It worked like a charm. My pain went from a 9 to around a 2 or 3. I will be on it the rest of my life but who cares. He had to call my problem neuropathy in order to justify giving me the drug. Please consult your doctor about this drug. It may help. Wishing you all the best.
