I had symtoms of headache ,weakness, dizziness ,head rush,faint feeling,and then a tingling that took over starting from the head and face and went down whole body like a wave causing muscles to draw up,numb, and paralyze in its path especially in the face, tongue and both hands. It went away and came back a few times over a few hours. This was a one day occurance 5 years ago and it has not come back, but what was that?
