Causes of a migraine

We don't really know the causes, however one theory is the stimulation of the temporal area by several factors. Some inflammation occurs around the trigeminal nerve which encloses blood vessels of the brain. We think that pain occurs by the dilatation of blood vessels.

Migraine main triggers


As women's hormonal secretion, sleeping and appetite are depending on temporal area, women menstrual periods, ovulation, delivery, menopause, change in wake-sleep pattern and food cravings are migraine triggers.
Also, as the temporal area commands the autonomic nerve, other factors like stress and relief from stress, bright lights, strong smells, crowds, noise pollution, weather changes, the change in temperature or humidity and alcohol are migraine triggers.

Treatments to relieve a migraine headache


If you want to relieve symptoms of a migraine, we recommend you to cool the painful spot with a cold towel. If you warm or rub the painful spot, it might have an opposite effect. Moreover, when you have a headache, we recommend you not to take a bath. Rest in a quiet, dark room and try to sleep a little may calm the symptoms. When the pain is bearable, you can take nonprescription drugs.

Type of treatments for migraine headache


If cooling the area doesn't help and you have problems to cope with daily life, we recommend you to talk to your doctor or to the nearest internal medicine doctor. If symptoms don't get better, you should see a specialist (headache clinic or a neurologist).

The main treatment of migraine headaches is drug therapy. Triptans has the function to reduce inflammation around the trigeminal nerve and constrict blood vessels. Triptans are most effective when taken early just when the pain has started.

If the start of migraine headache is not very clear, try to bow or shake your head to the right and left. If pain increases, we think that it is time to intake triptans.

Triptans comes as migraine tablets, one to be in dispersible form and one in ingestible form. For those who have nausea and cannot swallow, there are nasal spray preparations.

There is also an injection form to be injected by oneself in the thigh. Its effect is immediate and could be effective even if you vomit or if your headache has already begun.

In case you can't intake triptans?


Triptans have the function to constrict blood vessels. For this reason, it should not be used by those who have either a past history or risk factors, of cerebral infarction, angina・myocardial infarction. There is a risk of aggravation of these diseases. Besides, we recommend people to refrain of the use of triptans in case of high blood pressure or impaired liver function.

For people who can't use triptans, we recommend the use of NSAIDs (Non-Steroidal Anti-Inflammatory Drugs). For pregnant women and breastfeeding women, see your doctor to discuss about the best treatment.

Headaches drugs are efficient if you use them correctly. Be careful not to overuse them by your own decision, there are risks of over-using headaches medications. There is a possibility to use preventive drugs in some cases. Such as people having headaches 2 to 3 times a month, headaches lasting a long time which unable people to realize daily tasks. People using triptans which are not efficient, or people anxious to have migraines can also take preventive drugs if wanted.
