My first autonomic symptoms started a year before the major sensory ones. I would have random times of vertigo, orthostatic hypertension which just kept getting worse, palpitations, agitations, confusion, and an electrical surge feeling just as I was falling asleep. I started noticing that my muscles wouldn't recover from work outs and I became weaker and had some random numb spots in legs and tingling in left foot and in my hands when elevated. It took a year for all this to develop into full body and face sensory pain and symptoms.
