Doctor may evaluate: Nausea, body aches, light headedness, headache, etc... Are called non-specific flu-like symptoms, because they can occur with a variety of illnesses (such as viral or bacterial infections). Whether a person goes to his doctor right away or waits a day or two depends on the severity of symptoms, the person's underlying health, the chance that it could be something more rare or more serious, etc...
