MIGRAINE: MORE THAN WHAT YOU THINK!

Migraine is medical condition that involves recurrent severe form of headache and other symptoms. The headache in migraine is throbbing or pulsatile sensation limited to one side of the head (the entire head may be involved too). Symptoms may include sensitivity to light and sound, nausea, vomiting and difficulty speaking. Migraine pain most commonly affects the forehead area. It’s usually on one side of the head, but it can occur on both sides, or shift.

Most migraines last about 4 hours. If they’re not treated or don’t respond to treatment, they can last for as long as 72 hours to a week.

MIGRAINE SYMPTOMS

Symptoms in migraine are in stages. Stages which may not necessarily follow the sequential order are:

About 60% of those who have migraines notice some symptoms hours or days before the headache. These symptoms include: lack of appetite or food craving, mood change, severe thirst, bloating, constipation or diarrhea, being sensitive to light, sound or smell.

This stage involves visual sensation or feeling of impending doom. This stage is over a period of 5 – 20minutes and last less than an hour. One may see: flashes of light, wavy line, black dots, tunnel vision, not able to see at all, numbness on one side of the body, inability to speak clearly, having ringing sensation the ears, and changes in taste and smell.

Stage 3: Attack stage

A migraine headache usually starts as a dull ache and later becomes pulsatile or throbbing pain. The pain can move from one side of the head to another, can be in front of the head or can affect the entire head. About 80% of the patients experience nausea along with the headache while about 50% eventually vomit. Some may feel faint or pale and clammy. Most migraine headaches last 4 hours, but severe ones can go more than 72hours.

The International Headache Society recommend the “5, 4, 3, 2, 1” criteria to diagnose migraine without aura. This number series stands for:

  • having five or more attacks, each with a duration of 4 hours to 3 days
  • the headache having at least two of the following qualities:
    – occurring on one side
    – pulsating
    – causing moderate-to-severe pain aggravated by activity
  • having at least one additional symptom, such as:
    – nausea
    – vomiting
    – sensitivity to light
    – sensitivity to sound

The doctor may recommend imaging or other tests to exclude other causes of symptoms, such as a tumor.
