The causes of head pressure include allergies, brain and ear infections, head injury, headaches, inflammation of the sinuses, and brain tumors, as stated by Healthgrades. Diseases and conditions such as seizure disorders and meningitis also result in head pressure.
Common conditions that cause head pressure include allergies, stress and respiratory infections, according to Healthgrades. Migraine and tension headaches; muscle tension in the neck, jaw or shoulders; and sinusitis, which is inflammation of the sinuses by allergies or infections, can all result in feelings of head pressure.
Abnormal pressure in the skull is medically referred to as intracranial pressure, notes Healthgrades. Intracranial pressure may be caused by brain tumors, head injuries, meningitis, intracranial hypertension, inflammation of the brain that results from infection, rupturing and bleeding of a brain blood vessel, increased levels of fluid in the brain, and brain hemorrhage, which is bleeding in the brain due to trauma, the consumption of blood thinners or stroke.
Individuals who experience head pressure and its symptoms should consult with medical experts to avoid severe consequences, advises Healthgrades. Persistent head pressure may possibly result in coma, stroke, respiratory arrest, seizures, paralysis and permanent brain damage, which may affect speech and cause poor intelligence and thinking.
