1 Ethmoid Sinus Cavities â are located in-between the eyes. 2  An infection in these sinus cavities can cause pain in-between the eyes. 3  This pain can extend to the forehead and cause headaches. 4  Frontal Sinus Cavities â are found above the eye and eye bone.
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.
