What are sinuses and sinus headaches?
Sinuses are air-filled cavities (spaces) located in the forehead, cheekbones, and behind the bridge of the nose. The sinuses produce a thin mucus that drains out of the channels of the nose. When a sinus becomes inflamed, usually as the result of allergies or an infection, the inflammation will prevent the outflow of mucus and cause a pain similar to that of a headache.
What are the symptoms of sinus headaches?
Sinus headaches are associated with a deep and constant pain in the cheekbones, forehead or bridge of the nose. The pain usually intensifies with sudden head movement or straining. The pain is usually accompanied by other sinus symptoms, such as nasal discharge, feeling of fullness in the ears, fever, facial swelling, sinus pressure and sinus congestion.
Whether your headache symptoms can actually be attributed to the sinuses will need to be determined by your doctor. If your sinus headache is caused by a sinus blockage, such as an infection, you will likely have a fever.
