A migraine is a headache that is associated with severe pain that lasts several hours and can be responsible for extreme symptoms in people who suffer from them. It is not completely known why some people suffer migraines but sometimes there are triggers such as--allergies, stress, certain foods, environmental triggers or even a genetic basis. Pain receptors are stimulated in the brain due to a restriction of blood flow in the brain and then a muscle relaxation occurs which leads to increased blood flow. Cranial vessels leak and tissue inflammation occurs. Some see auras when migraines occur, this has to do with the field of vision looking hazy or wavy during the migraine. Treatment includes finding a dark and quiet area to lessen the effects of the migraine as well as acetaminophen, aspirin and even caffeine to help reduce the symptoms. For more severe migraines, there are other drugs and nasal sprays that can help as well as biofeedback and avoiding food triggers.
