How do i get rid of my cold and congestion?

Time: If you have a simple common garden variety viral upper respiratory infection, only time will make you feel better. If you have congestion due to allergies, you'll need to avoid those specific allergens, possibly seasonal, so we're back to time. Or take an anti-allergy (antihistamine) medication, some of which are available over-the-counter. But beware that everything has side effects. Go c ur doc.
