twice in past 2 weeks, while driving, I experience full body feeling of swelling, tingling with acute vision of an event that is familar to me, followed by nausea, disorientation, fatigue, body tingle as well as tingleing along the jaw line. The vision last for a couple of minutes (I am still aware of my surrounding) but the nausea last for several hours, then I get a headach for remainder of the day. My thought process is slowed down, processing information is also slowed. I have MS (3 years) take Rebif and Im yrs old. Is this a type of seizure??
