Hello, I am new here. Have any of you had abnormal sensations and internal tremor as a first symptom? I had pin-pricks and electrical shock sensations all over body, then an internal tremor on one side (calf of leg) and in chest & abdomen, unfortunetly cannot be dx'd because symtoms cannot be seen (hence name, invisable). Atually even b4 these symptoms and think I was developing RLS, now it is quite obvious. I am considering getting Flora-Dopa Pet Scan, the suspence is killing me (literally)!!
