Sinus headaches are the result of congested passages of air-filled passages in your forehead, nose, and cheeks. They can occur on either side of your head causing a sharp pain in your head and the entire sinus area. Sinus headaches may be a sign of a serious condition called sinusitis. If they happen occasionally or in specific seasons, they are likely due to allergic reactions. Many different reasons can trigger the headaches in different individuals. Luckily, there are equally many alternatives to treatment of the headaches.
Sinuses are the air-filled spaces inside your forehead, cheekbones, and bridge of your nose. These are sensitive parts of your system easily irritated by various foreign intrusions. Various allergens cause inflammation of the sinus area causing them to swell, release more mucus, and blocking the draining channels. When there is build-up of pressure in your sinuses, you will experience the familiar sharp pain in your head that lingers until the allergens are eliminated.
