What is migraine?
A migraine is a headache syndrome. It is thought to be a result of a physiological process called “cortical spreading depression”. What this means is that something triggers a pain and when it becomes a migraine the pain has activated nerve cells on the scalp. This then goes on to develop into the pain that is commonly associated with migraine. This is usually a throbbing pain and can be extremely severe and debilitating.
