Sinusitis ![]() Nearly everyone has experienced a sinus problem. A stuffy head with pain and pressure around the face are common symptoms of sinusitis due to colds, allergies, or a sensitivity to airborne pollutants. The sinuses are air-filled cavities inside the bones of the face that drain into the nasal cavity. Blocked sinuses don't drain properly, causing pressure and pain. Sinusitis–an infection of the sinuses–can be classified as acute, which means that it comes on suddenly, often right after an upper respiratory infection such as a cold or flu. Or sinusitis can be chronic, meaning that it is an ongoing problem. In either case, when the discomfort of sinusitis is severe or the symptoms persist, a comprehensive medical examination with appropriate treatment is recommended.
