Hi! My roommate has terrible NVD, is sweating a lot, and has told me she is experiencing high pitched ringing in her ears intermittantly, and is going "numb and tingly" while she is vommitting and having diarrhea. I am not there in person, so I cannot assess her in person. She is having cold sweats and hot flashes as well. She has had these symptoms for the last 4-5 hrs. I'm trying to determine if she may need to visit an ER, because she sounds pretty dehydrated and the numbness is worrisome.
