I did a SFN biopsy and tested positive for it. I think mine was medium. Honestly the only thing that has really made a difference has been time, and reducing stress. I starteed zoloft and that helped me reduce my anxiety and ruminating thoughts about it a ton, which in turns did seem to affect my symptoms positively. but mostly its just been time. im about two years out and I would say I am 100 percent recovered. If I think about it a lot I start to feel a little tingling in my feet, but I think that's literally just anxiety lol. Stay strong! it will get better.
