My husband broke out in a hot sweat yesterday, but seemed to feel all right after he cooled down, but had felt a bit lightheaded during the day when he got up from a sitting position. Then the dizziness disappeared. After going to bed last night, he woke up about 2:00am with his body moving unvoluntarily (I was awakened & saw his arms shaking /thrashing) . That ended & he got up, feeling lightheaded again & went to the bathroom. He said his body feels strange, but has no pain. We are here in FL right now on vacation & I m concerned whether we can wait till morning to seek urgent care.
