Potential causes of pressure headaches

Pressure headaches are one of the common forms of headaches. An episode can arise if blood, mucus or cerebrospinal fluid builds up and increases the pressure. A tumor that forms in the brain might also trigger this type of headache. Stress, migraines and abrupt changes in the air pressure can also cause pressure headaches.

Sinus infection

A sinus infection can also trigger pressure headaches. The headache is likely to occur in cases where respiratory infections or allergies are responsible for the sinus congestion and inflammation.

A healthy sinus allows mucus to drain but if they are inflamed, the mucus is blocked within and causes intense pressure. The indications of a sinus infection include greenish or yellowish drainage from the nose, fever, red and swollen nasal passage as well as fatigue. The sinus pain is worst behind the eyes and forehead area. Abrupt motions can aggravate the pain and usually worse in the morning due to the buildup of mucus in the sinuses overnight.

Pressure headaches are considered as a usual indication of brain tumors. The developing tumor triggers pressure within the head. It is likely for a tumor associated to headaches to be worst in the morning.

These headaches are likely to become frequent and worsen over time. Aside from the headache, an individual with a brain tumor will also experience nausea and vomiting. In addition, the headache worsens when coughing, bending over or sneezing.


Hydrocephalus is a condition where cerebrospinal fluid builds up within the brain, resulting to intense pressure that leads to headaches.

The condition is prevalent among infants but can also develop among older children and adults. It can also occur after bleeding in the brain.

In some cases, hydrocephalus can be hereditary or brought about by ailments in the production of cerebrospinal fluid.
