When do you go in to the doctor?

Has 102 degrees Fahrenheit temperature since Wednesday September 29, 2021.

Complaints nausea, fever, head hurts eye's feel strained.

I'm not sure what to do I give Tylenol about every eight hours. Age six

My concerns are when is it time to go to the doctor?

If it's a virus nothing can do but rest.

So with Colds, Flu, Coronavirus they are viruses so not sure what to do
