question: My girlfriend went to bed up shivering very violently (teeth chattering) saying she was very cold but her body is very warm. I dont have a way to take her temperature but she is probably running a fever. She got bundled up under a number of blankets and fell asleep, but awoke a few hours later to violent shivering. After 20 -40 minutes, it subsides and she falls back asleep. Should I take her to the hospital?
