Cindy, my experience with SFN sounds exactly the same. I wondered if my taking Tamilu had any connection. I have the burning, tingling in my hands and feet along with the muscle twitching in my legs and night time feet/leg cramps. It came on suddenly 18 months ago. I initially experienced some other slight transient symptoms and and still do but they cine and go. I take 300mg. gabapentin at bedtime and various supplements during the day which I think help. I exercise and drink no alcohol, but I have no weakness, and feel that my neuropathy has improved over time. I have had a few flare ups but possibly with the virus- caused neuropathy the affected nerves improve with time? My neuro classified me as ideopathic but after ruling out other causes believe mine was caused by a virus. I hope you also improve over time.
