if it's lasted this long and isn't getting better it might be something else like allergies the flu or something else. while you wait to talk to a doc or urgent care get plenty of garlicky chicken soup use some afrin or similar nasal spray to open up your nasal passages and take lots of hot steamy showers. also drink a lot of black tea with honey and lemon. rest as much as you can. you'll feel better.
