A migraine is a headache that can cause severe throbbing pain or a pulsing sensation, usually on one side of the head. It’s often accompanied by nausea, vomiting, and extreme sensitivity to light and sound. Migraine attacks can last for hours to days, and the pain can be so severe that it interferes with your daily activities. Migraine will likely get worse with physical activity, lights, sounds or smells. It may last at least four hours or even days.

Stages of Migraine:-
The four stages in chronological order are the prodrome (pre-monitory), aura, headache and postdrome. About 30% of people experience symptoms before their headache starts.

The phases are:
Prodrome: The first stage lasts a few hours, or it can last days. You may or may not experience it as it may not happen every time. Some know it as the “preheadache” or “premonitory” phase.
Aura: The aura phase can last as long as 60 minutes or as little as five. Most people don’t experience an aura, and some have both the aura and the headache at the same time.
Headache: About four hours to 72 hours is how long the headache lasts. The word “ache” doesn’t do the pain justice because sometimes it’s mild, but usually, it’s described as drilling, throbbing or you may feel the sensation of an icepick in your head. Typically it starts on one side of your head and then spreads to the other side.
Postdrome: The postdrome stage goes on for a day or two. It’s often called a migraine “hangover” and 80% of those who have migraines experience it.
