Would love some input and guidance. Neuro told me I most likely have SFN but felt it was not necessary to do a SFN biopsy. Told me to return in 6 months. Told me not to believe everything I read on the internet regarding SFN. Told me supplements will not help. It seems as though many people are getting good results with the right supplements. Is this something that could help me? Shortly after the neuro, saw a new PCP, who DXed MCTD. New PCP did not order any new tests and told me that I did not need to take the usual meds for MCTD or see a rheumy. Have had SFN symptoms for 3+ years. Have very few MCTD symptoms. Can MCTD cause SFN? If I really do have both of these conditions, what can I do to improve the SFN symptoms? Also, would love to hear from anyone who has MCTD...what are your symptoms and how do you manage them?
