The exact cause of migraines is still somewhat unknown; the current understanding is that there is a temporary change in the chemicals and blood vessels of the brain.
A migraine is typically experienced as a severe headache, often with a throbbing pain in the front or sides of the head. Some people have other symptoms including nausea, vomiting, and extreme sensitivity to light, sound or smells. Migraines can last from a few hours to a few days.
There are different types of migraine. There are migraines with aura, which is where there are warning signs of the migraine in the form of visual disturbance such as seeing spots, lights or blurred lines. There are also migraines that occur without warning, and it is even possible to have a migraine aura without the accompanying headache.
There are also many different possible triggers for migraines. These can include, stress (and how stress is handled), food and drink triggers, sleep patterns, hormones and tension; especially in the neck.
In order to manage migraines in a regular sufferer, identification of a specific trigger is essential. Behavioural or lifestyle changes playing an important part in the treatment, such as avoidance of certain foods or maintenance of a regular sleep pattern. Chiropractic treatment also has the ability to alleviate some contributory factors or after effects including relieve of restriction in movement of the neck, muscle tension in the neck, upper back and shoulders and helping correct any postural issues that may influence the occurrence of both migraine and tension headaches.
