Is it normal to have headaches & feeling nauseous all the time since day 1? Also, slight fever now.

I was having 2-3 days of high fever (38+) out of the blue (not someone who will get fever thou). Im also feeling super nauseous but i cant vomit (makes it even worse) my headache is like exploding i dont feel like doing anyting! Its so heavy…

Headaches and nausea is normal I guess! Your temperature will be higher than normal but I don’t think a fever is normal 😅
