Please don't go to the ER until you try some OTC cold medicine first! With those symptoms, you would probably be left sitting in the ER for hours and hours as a non-emergency and it would be stupid expensive in the end. You would do better to just rest a lot at home today. Try some steam, too. Antibiotics won't help a cold, and you should avoid them unless you know you have an infection. Depending on where you are, you might just have hayfever or allergies. It's really, really bad in the midwest right now and your symptoms are typical.
