Nausea and sore throat can be caused by a cold (due to a bacterial infection). There are bacteria that cause upper respiratory infections and settle in the throat. Sore throat is common during such an infection. Infections also tend to cause upset stomach and can cause nausea.
Constant mild nausea can stem from physical trauma such as brain injury or concussion or from meningitis, an infection in the lining of the brain. Nausea also can be a side effect of medications. Cancer treatments such as chemotherapy may cause constant mild nausea and a frequent urge to vomit. This term is misleading, though, since nausea can strike at any time throughout the day and may or may not be accompanied by vomiting.
