Hello, I'm a newbie! Just turned 49 and have suffered with neck and head pain for 3 years. Pain Management performed several cervical and occipital radio frequency ablations over the past few years which had been less and less helpful with more side effects. Finally diagnosed with SFN via skin biopsy in February because I begged for help knowing something was wrong with me neurologically. So far tests are only indicating B12 deficiency. I cant help but wonder if all of my ablations created or added to SFN. You know, which came first thr chicken or the egg?! Anyone have any knowledge on this?
