Hi doctor,
This is the 4th it has happened to me in the past 3 months. I woke up at 3 or 4 am due to feeling nauseous and wanting to having a bowel movement. Then I get up throwing up, I have cold sweat, numb hands and feet, dizziness, breathing hard nearly passed out. My face and hands feel cold, but when I touch them, it's normal temperature. What is wrong with me? Thank you.
