Migraine Symptoms include a severe headache that occurs usually on one side of the head but sometimes can be on both sides of the head but it is very rare. There is a vast difference between the ordinary headache and migraine. Other migraine symptoms include a sensitivity to light, vomiting, nausea and sensitivity towards any kind of sound.
A person suffering from migraines will always like to relax in the dark and quiet place and most of the times relief can be obtained only when vomiting takes place. It is a recurring condition which has no fixed timings or periods but can occur even in sleep.
There is no permanent cure for migraine symptoms as until now the actual cause of a migraine has not been established. In the past it was believed that migraines was caused due to some chemical changes in the blood vessels present in the brain. Recent research has propagated the theory that the chemical changes do not occur in the blood vessels present in the brain but it is the brain which is affected by the chemical changes. The chemical changes mostly occur through the nerve pathways which function within the brain.
