Fever goes away during sleep then comes back during day

[anxdesert]

I’m dealing with some sort of respitory virus right now, thought I was getting better yesterday now I feel like crap again today. The really weird thing is I wake up and no fever then as the day goes I start to get the fever again. Had anyone ever had that happened?

Well here we go again woke up this morning with 98 and thought the day it’s been slowly climbing and now it’s 100.1 took 2 ibuprofens an hour ago and no change. Damn it!
Freaking out.

That's how fever works.

Yeah, body temperature rises naturally in the day, peaking at in the middle of the evening, so your fever is behaving as you'd expect.

Also, worth bearing in mind that unless you have previously tracked your body temp in the evening, you don't have a baseline reading of what's normal for you.

It probably wouldn't be over 100, but it could be 99...
