Sinusitis is caused by infection of one or more of the cranial (skull) sinuses. These are the bony inner structures of the skull. Acute sinusitis lasts for days up to three weeks. The International Headache Society's criterion of purulent discharge and acute febrile illness is indicative of acute sinusitis (sinus headache). The site of the pain varies according to the location of the infection. Maxillary sinusitis pain is mostly in the cheek, gums, teeth and upper jaw. When pain is presented between and around the eyes this is referred to as ethmoidal sinusitis. Frontal sinusitis pain is seen in the forehead and sphenoidal sinusitis presents with pain at the crown of the head. The pain often has a a dull aching quality which is worsened by bending. Very rarely complications can occur such as meningitis or abscesses.
Post Herpetic Neuralgia Shingles (herpes zoster virus) can cause pain resulting from various cranial nerves. The pain may start during an acute rash of herpes but the main problem is pain that persists after the herpes rash has gone. Common symptoms include a constant deep pain, with repeated stabs, or needle pricking pain. Even light touch can trigger these symptoms which may be accompanied by itching. Half of patients have no pain after three years.
