Migraine is not just a headache, it is usually a full blown attack. Symptoms are recurrent, with attacks coming on out of the blue and lasting from several hours to several days. Migraine without aura, or common migraine, consists if a severe, throbbing, pulsating or hammering headache on one side, usually with abdominal symptoms. These include loss of appetite, nausea, vomiting, dislike of food, constipation or diarrhea. 9 out of 10 sufferers experience this form of migraine. Migraine with aura, or classic migraine, include visual disturbance as well as any or all of the symptoms of common migraine. Vision can be distorted with shimmering or flashing lights, strange zig zag shapes or blind spots. 1 in 10 sufferers get this form of migraine. Cluster headaches, attacks occur in clusters every 12 to 18 months. Severe pain is felt around one eye, often at night, for 1 to 3 weeks. The eye looks red and watery with engorged veins. The nose may become blocked up on the same side.
The exact cause of migraine is not fully understood. Attacks seem to be linked to chemical changes in the blood vessel walls and nerve celss within the skull. The most important chemical involved is called serotonin (5 hydroxytryptamine or 5HT for short). Migraine headache occurs whn blood vessels widen so that tissues become congested. Serotonin is in short supply during this phase.
Migraine can often be relieved by applying a magnetic patch to the middle of the forehead. Once the migraine has gone, the patch may be removed. Magnetic patches can also be applied to acupunture points over or near the site of pain or select the points which most closely relate to the site of discomfort.
