You don’t feel temperature you can only feel the rate of energy exchange. In most case, this give us a good approximation of the temperature, after all the colder something is the faster it will suck energy from you and the colder it will feel to you.
But when you have a fever your temperature is high, and energy go from high energy to low energy, so your heat transfer through conduction to the environment faster when you have a fever, than when you don’t have one. So even if you have an higher temperature your body feel more energy leaving it, which is the cold feeling.
The difference is the the heat come from inside your body by burning more fuel and the energy will flow toward the outside. When you feel hot it’s because the energy is coming from the outside and flow toward your body when you can feel the rate of energy transfer.
