Hi dcd2103,nI am not sure what caused my P/N I had hep c that was giving me problems 15 years ago while getting treatment I was diagnosed with P/N the neurologist said hep c caused it and the hep c doctor said he was full of beans and that they always blame hep c, so I am still not sure but I myself leaning toward the hep c causing it. I cleared the hep c 15 years ago but this P/N hung on, it was not to bad up until a year ago now it is coming on me fast almost every month a new symptom. I don't know if it is due to having it so long and being 61 years old or if something else being its driving force or all 3. This burning body stuff so far is the worse so that's why the r lipoic acid question. He did not tell me anything [my neurologist] just gave me a test, said I had sensory nerve damage and walked out, so I am not sure what type I have?
