How long does it last? Anywhere from 72 hours to five days if it's a severe infection.
What causes it? Allergies, cold and flu or sinus infections. When you're feeling congested and all stuffed up in the nose, the build up of fluid can cause the headache feeling. But is generally worsened by head movements like bending over to pick something up.
