Causes of sinus headaches

The sinuses are small air spaces in the skull, found behind the nose, eyes and cheeks. They open out into the nose, allowing mucus to drain and air to circulate normally.

When the lining of the nose and upper airways becomes infected for example, with a cold the infection can spread to the sinuses and cause them to become swollen.The small opening from the sinuses to the nose can become blocked, which leads to a build-up of pressure inside the sinuses. This is known as sinusitis.

For some people with sinusitis, the pressure builds up to such an extent that it causes pain, or a sinus headache.

You may feel stuffy and congested for a while, but it normally gets better once the cold goes away.

Sinusitis and sinus headaches can last much longer. This usually only happens if bacteria infect the trapped mucus, or your sinuses repeatedly swell up because of an allergy .
