A sinus headache is a type of headache that is often associated with a sinus infection or inflammation of the sinuses. The sinuses are air-filled cavities located behind your cheekbones, forehead, and nose. When these cavities become inflamed or blocked, it can cause pressure and pain around your eyes, cheeks, forehead, and nose.
Symptoms

Causes
- Sinus infection (sinusitis): This is the most common cause of sinus headaches. Sinus infections can be caused by viruses, bacteria, or fungi.
- Allergies: Allergies can cause inflammation in the sinuses, leading to sinus headaches.
- Nasal polyps: Nasal polyps are noncancerous growths in the lining of the sinuses that can block the sinus passages.
- Deviated septum: A deviated septum is a condition in which the wall between the nostrils is off-center, which can block the sinus passages.
- Dental infections: In some cases, dental infections can spread to the sinuses and cause sinus headaches.
