Headaches that occur when the head is lowered may be caused by rhinogenic headaches, hypertensive headaches, and increased cranial pressure. Most rhinogenic headaches are caused by acute inflammation of the sinuses. Patients may have long-term symptoms of nasal disease, such as nasal congestion and runny nose, and the headaches are mostly deep headaches with a dull pain. Patients with hypertensive headaches usually have increased blood pressure, which leads to a decrease in the elasticity of the blood vessel walls, and the symptoms may worsen during mood swings. The presence of cranial injury, brain tumor, and bleeding can lead to increased intracranial pressure, and the headache will worsen in the morning and when coughing or bending over, and needs to be treated with diuretics in time.
