Thank you so much for replying to my post. Sounds like you have been through a lot with a little results from lipoic acid. I did have many blood tests as well and they considered Lyme disease for a while still inconclusive. Your pinpricks all the time must be impossible My problem is that my toes have a mind of their own and cause imbalance when I walk and pain after just a few minutes of standing or walking. I saw a video on YouTube concerning the difficulties of trying to find causes for peripheral neuropathy and therefore the idiopathic diagnosis. She said that there is no such thing as idiopathic. In Latin it means an idiot. She is in Boston and I am in Plymouth and I'm trying to get an appointment to see her. She developed a list of tests that doctors should use to try and rule out certain causes. This was 7 years ago and the list is being used today I believe. The doctor is Dr Oberlander. I will give you more information as I go back and find it and forward as I see her.
Thanks so much for sharing. I can wish you good luck and hope that the pinpricks are gone.
