Hyperhidrosis -- dehydration -- elevated BP & seizure (unable /no strength to move any muscle for 5 min, though fully conscious) is this a possible sequence? The person had no history of seizure earlier. She was feeling very hot, complaining about being extremely tired and sweating a lot before the event, which happened 4 days ago. Had a heavy head for couple of days after that, now completely normal. The only medicine she currently takes daily is Eltroxin (Levothyroxine) 75mg daily. Is this most possibly one-off event, being careful about not getting dehydrated and taking ample rest would do? BTW, visiting a doctor day after tomorrow regarding this.
