Hi...I am patient at Mass General with idiopathic NLD SFN. For those interested in this disease there is a video by Dr. Anne Louise Oaklander posted on the MGH neuropathycommons.org website. It is under "For Patients and Physicians", "Video Lectures", "A Name for the Pain". It is very informative and comforting to know that someone "gets it". Let me know if you have trouble finding it.
