Why do fevers give you chills?

Sometimes when we get sick, our body reacts by cranking up our internal temperature to make a fever. This helps get rid of invading bacteria or viruses. But sometimes when you have a fever, you feel cold instead of hot. What’s up with that? We asked ER doctor Joe Alcock to help us find the answer.
