I can relate to the mysteriousness of your symptoms. Here I am without any diagnosis. They say to avoid stress when dealing with autoimmunity;however, I find it stressful that doctors cannot figure out how I ended up with peripheral neuropathy. I do not fall into any of the categories i.e. diabetes or others. I had a bad sinus infection and took two days worth of methylprednisolone and voila--here I am with tingling, numbness and wobbly legs. My muscle tone is also messed up. Seeing doctors is difficult--more stress--and no resolution. My sympathies and support to those like me who are on a merry-go-round.
