Common cold?: Go see your local primary care physician and have an exam. They may treat with antibiotics if this is strep, but more likely viral or allergic and you need saline irrigation with a neti-pot, decongestants, and an anti-inflammatory. Good luck and feel better soon.

Infection: It sounds like you could have sinusitis or allergies or possible cold as well. Going to the doctors to be evaluated will help you receive a diagnosis and proper treatment.
