What are auras and how many people with migraines get them?

ANSWER

About 25% of people who get a migraine have visual changes that are known as auras. You may see spots, wavy or jagged lines, or flashing lights. The symptoms usually ease in under an hour.

Auras can also happen before a migraine headache hits, serving as a warning sign. In some cases, you may get an aura without a headache.
