Migraine is a neurological disorder characterized by recurrent and severe headaches, often accompanied by other symptoms such as nausea, vomiting, sensitivity to light (photophobia), and sensitivity to sound (phonophobia). Migraine headaches can be disabling and affect an individual's daily life, leading to decreased productivity and quality of life during the episodes.

Key features of migraines include:

Throbbing or pulsating pain: Migraine headaches typically involve intense, pulsating pain on one side of the head, although it can affect both sides in some cases. The pain may last for several hours to several days.

Aura: Some individuals experience an "aura" before or during the migraine attack. Aura refers to transient neurological symptoms, such as visual disturbances (flashing lights, blind spots), tingling sensations, or difficulty speaking. Not all migraine sufferers experience auras.

Triggers: Migraine attacks can be triggered by various factors, which differ from person to person. Common triggers include stress, hormonal changes (in women), certain foods (e.g., chocolate, cheese), lack of sleep, strong odors, bright lights, and weather changes.

Phases: Migraine headaches are often divided into four phases: prodrome (premonitory symptoms like mood changes or food cravings), aura (if present), headache phase, and postdrome (recovery phase characterized by fatigue or euphoria).
