What is it? Throbbing pain to the head or isolated to one side, followed by sensitivies to light and sound. These are probably the nastiest of them all and can quickly cause nausea, vomiting and visual disturbances.
How long does it last? Anywhere from four hours to three days, and can happen a few times a month. Ouch!
What causes it? The exact cause is unknown, but genetics are said to have a place. So if your mum or dad gets them, chances are you will, too. Other triggers include stress, weather, and sleeping and eating patterns.
Treatments? Standard over-the-counter meds like ibuprofen might help, but chronic migraine sufferers will usually be prescribed a drug from the triptan family by their physician. And it's best to find a dark room with a comfy bed to lay down in.
