Symptoms

Many people who have migraines feel vaguely unwell for a day or two beforehand.

Some people get what is called an aura. Some people see flashing lights, some find problems with their speech, and some feel pins and needles in their arms and legs. This can happen before or during a migraine.

When the headache starts, it is usually severe. Your heads throbs, and it might hurt to see bright lights or hear noises. You might feel sick, and you might vomit. This can last anywhere between a few hours and a few days.

Causes

Nobody knows what causes migraines.

They can run in families, but don’t have to.

Some people find that migraines are triggered by certain things such as:

• cheese, chocolate, red wine and monosodium glutamate (MSG)
• stress and changes of routine
• changes in the weather
• hormonal changes and the oral contraceptive pill for women.

Diagnosis

Your doctor will diagnose migraines by talking to you and examining you. There is no specific test to diagnose migraine. However your doctor may do tests to exclude other causes of headache.

Treatments

If you suspect you are getting a migraine, take pain-relieving medicines straight away. Some people find they can prevent the headache by treating it early. Talk to your doctor or pharmacist about options.

During the headache, rest in a quiet dark room. Get as much help as possible to take over any responsibilities with work, family and so on.

If you get migraines fairly often, then preventive medicines may help.

If you have just started getting migraines, then keeping a diary about them would help you understand when they happen, and what triggers them. That may help you prevent them.
