The possibility of a migraine headache can easily become the worst fear of anyone who has ever suffered from one. These debilitating headaches are believed to be caused by changes in the levels of serotonin in the brain. When the levels are too low, this causes the blood vessels to swell, and this swelling causes quite a bit of pain. The level of serotonin that your brain produces is determined by many different things, including foods, light, estrogen, and blood sugar levels.

migraine headaches know that the pain can become incredibly intense, literally preventing them from going about their day-to-day lives. Different people experience different levels of pain with their migraines - no two are alike. Symptoms of a migraine headache may include nausea, vomiting, blurred vision, spotty vision, sensitivity to light, sound and smells, intense throbbing pain in various places on your head, feelings of exhaustion, confusion, being too hot or too cold, having a stiff neck and shoulders, dizziness, or feeling light headed.
