What are the main causes of pain and pressure in the forehead and eyes?

The main causes of pain and pressure in the forehead and eyes include severe hypertension, sinusitis, etc. First, it is important to consider whether the patient has severe hypertension. In such cases, cerebral vascular spasms may occur, leading to a sensation of distension and pain in the forehead. If hypertension is particularly severe, it can increase intraocular pressure. Typically, sinusitis causes excessive secretions discharged from the nasal cavity, as well as nasal congestion; in severe cases, it may lead to cerebral ischemia, hypoxia, and forehead pressure or pain.
