Hi @johnbishop. The article link you shared is right on point. I can tell you from experience the EMG and any other test other than the skin punch biopsy will not give the patient a proper diagnosis. I was sent for multiple EMG’s where they would twist my legs like a pretzel haha until they could get a reading. None of the EMG tests over 3 years ever showed signs of SFN. Only when I sought a second opinion, waited six months for an appointment to have the skin biopsy and the QSART test done, did my life change in a positive way. Please don’t get me wrong, I was less than thrilled with confirmed SFN, however, at least now we had a course of treatment. As I’ve said before, Lyrica works really well for me. Many other meds (Cymbalta, etc) did not. Cannabis helps distract the brain. I encourage everyone with potential SFN to read the link shared by @johnbishop here. While it is from 2009, it is the most comprehensive, understandable article on that topic I’ve seen. I wish you all a positive, pain free day
