what causes pressure behind your eyes
Sinusitis: Sinusitis is a sinus cavity inflammation that causes pressure and pain behind your cheek bones or eyes. Other symptoms of sinusitis include fatigue, toothaches, fever, a stuffy nose, a reduced sense of taste, and tenderness in the front of the face.
In some cases pain behind your left eye can be due to a pressure headache and this is when you experience increased pressure in a specific area. The pressure in this area will surround the tissue as well as press on the nerve fibers and this combination leads to the activation of pain receptors.
