Migraine: One of the theories behind migraines is that they're caused by over-stretched blood vessels in the brain, which stimulate pain receptors and cause the pain. The features of migraine include nausea and vomiting, light and sound sensitivity and (often) an aurora preceding the headache consisting of visual distortions such as flashes of lights and "sparkles.".
