I don't know why, but every time before my menstrual period starts, I experience general weakness, dizziness, and headaches. I would like to know what causes this kind of periodic headache?

Cluster headaches are a type of recurrent disorder with a familial predisposition, characterized by headaches that occur in a regular, predictable pattern. These headaches may present as episodic, one-sided pulsating headaches accompanied by symptoms such as nausea, vomiting, and sensitivity to light. The pain may subside in a quiet, dark environment or after sleep. Each episode of a cluster headache typically lasts from 4 to 72 hours, and can occur several times a day, ranging up to tens of attacks per day.
The causes of cluster headaches are varied and may be related to menstrual cycles, lifestyle patterns, drug metabolism cycles, and psychological factors. For example, migraines in some women are closely related to their menstrual cycle; stress and work pressure may also trigger headaches. The metabolic process of certain medications can likewise lead to periodic headache episodes. Psychological factors, such as mental suggestion or recurring environmental exposure, people involved, may also induce cluster headaches.
If symptoms of cluster headaches occur, prompt medical attention is recommended.
