Sounds like a virus: If you develop fever, other symptoms or the above is getting worse would see a doctor asap. Otherwise use Acetaminophen (tylenol), fluids and bed rest and hope you will improve rapidly.

Influenza?: One of the most common afflictions this time of year --- see your doctor, as this could become serious.

A VIRUS: Can be a possible explanation for your symptoms. Keep hydrated and contact your doctor if no better within 1-2 days, and of course sooner if worse.
