Possibly...: You could have a viral infection that is causing your symptoms. Do you have any other symptoms like low-grade fever, nasal congestion, sore throat, fatigue, etc.? If this is a viral syndrome, you should start to feel better in a few days. Meanwhile, rest, drink plenty of fluids, take acetaminophen for discomfort. If.there is no improvement or if symptoms worsen, see your doctor.
