I have a fever of 100.4 and i had severe nausea since 4pm monday not vomiting yet i dont have diarrhea could i have the stomach flu or what is this or could this be from emotional stress can emotional stress cause fever and nausea?

Partly duplicates your other question. With this more detailed information, a gastrointestinal virus is a lot more likely than an emotional reaction. Get it touch with your doctor. Good luck.

Emotional stress does not cause fever. Fever of 100.4 and severe nausea most likely or a stomach virus infection or could be early signs of Covid infection. Recommend doing a HealthTap video visit for a specific diagnosis treatment and advice
