I really understand you. I know the situation. My first neuro. one of the best here said to me the first time I saw him that I'm in a panic and that's why I have all these sansatins. 3.5 years late - after the skin biopsy - I was DX with SFN.
The sansation are the same more or less for the last 5 years.

Try to learn to live with them - since they are going to stay for a while...
