Can emotional stress cause a 100.4 fever and severe nausea to feeling like youre going to throw up?

Certainly stress can cause nausea, but not fever. 100.4F (38.0C) is barely abnormal and likely not important if it doesn't continue or go any higher. Or you might have a mild viral infection. Contact your doctor if these symptoms continue or you otherwise remain concerned. 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
