What are night sweats?

What might be on your ddx if a patient presents with dizziness or lightheadedness in addition to a fever?

What is hyperthermia?
An elevation in body temperature due to loss of homeostatic mechanisms and inability to increase heat loss in response to environmental heat, as in heat stroke.
How are fever and hyperthermia different?
Hyperthermia is na elevation of the temperature related to the inability of the body to dissipate heat. Fever is a rise in temperature in response to endogenous cytokines.
