One clue was the temporal association; my neurological symptoms began within 2 weeks of the Covid vaccine. The rapid onset of peripheral neuropathy in a healthy, active person was fairly unusual. Some symptoms were unusual, e.g. the extreme aggravation of the nerve pain and numbness in my feet and calves when in a seated position. My initial EMG was normal and then the EMG rapidly deteriorated at the same time that my ANA titer increased 4-fold while my neurological symptoms were peaking. This finding indicates an autoimmune attack on my nerves most likely provoked by the vaccine. My sweat test for small-fiber neuropathy showed mild SFN damage over my entire body, which is also atypical in length-dependent peripheral neuropathy. In addition, most vaccine-injured people have roughly the same timeline with symptoms peaking at 8-9 months and then slowly improving. The strongest evidence is my continued, slow improvement after stopping the vaccines. For example, I lost my knee and ankle reflexes. At 2 years, my knee reflexes have returned, which is rare. Although there is no direct test that can prove I am vaccine-injured (except perhaps sending blood to Germany to measure spike protein levels), the combined indirect evidence is convincing.
