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.
Children may have a headache and stomach pain. Tonsillitis is an infection of the lumpy-appearing lymphatic tissues on each side of the back of the throat. Infections in the nose and sinuses also can cause sore throats, because mucus from the nose drains down into the throat and carries the infection with it. The most dangerous throat infection is epiglottitis, which infects a portion of the larynx (voice box) and causes swelling that closes the airway.
