Gidget here,
this is a slow board and you should have gotten better response, out of 57 people reading your post only 2 replys! I am from the lymphoma board and I have several neroumusclar dieases too.
Peripherial nero. pain does travel around and my husband and I have it too, he is a dibetic and got it that way, I am not a dibetic but I have it, I have had a spinal tap and a muscle biopsy with lots of blood work done by a neroulogist for dx. Get a referal and go to one for answers, no one should live in pain, there is medication to help stop the pain and I also go to a pain clinic where you can get the best care for pain relief to live life pain free!
take care, gidget
