High pressure

High pressure headache is a type of headache that is characterized by a feeling of pressure or tightness around the head. It usually develops slowly, beginning as a dull ache and gradually intensifying to a throbbing or pounding sensation. It can be accompanied by other symptoms such as sensitivity to light, nausea, and vomiting. It is most commonly caused by stress, dehydration, or changes in barometric pressure. It can also be caused by certain medications, or underlying medical conditions.
