My diagnosis is PNS.
I understand the tingling and burning that you are experiencing. To start, I am sorry to here of your condition. I was unable to walk. My neurologist prescribed low doses of Lamictal and increased milligram slowly. 15 years after the onset of this condition rarely do my feet burn. I continued my care with the Neurologist that first started my case.
Wishing you the best.
