ELI5: When we have a fever, our body heats up, but why exactly do we feel cold? Especially if it's a high fever like 103-104 range?

People are really bad at judging actual temperatures.

When you feel hot or cold, what you're actually feeling is the transfer of heat from or too you. 

When you feel cold, you're losing heat. When you feel hot, you're gaining it. 

So when you have a fever you lose heat to your surroundings, so you feel cold.


Side note: some things transfer heat better than others. Which is why metal feels colder than, for example, a woolly jumper. Even if they're the same temperature.
