    Migraine Aura

    Migraine Aura

    A migraine aura is a warning sign of an oncoming migraine headache. An aura develops gradually, usually within 30 minutes before a migraine headache starts, and consists of visual disturbances and physical sensations.

    Not everyone who suffers from migraines develops an aura. For those who do, common symptoms of a migraine aura include:

    • Visual changes. For example:
      • Zigzag or wavy lines
      • Flashes or sparks of bright or colored lights
      • Slowly spreading spots
      • Distortions in the shape or size of objects
      • Blind or dark spots in the field of vision
    • Numbness or a "pins-and-needles" sensation in one hand or the other.

    Other, less common symptoms of a migraine aura can occur, including:

    • Tingling or numbness around the mouth and nose or in the arms or shoulders.
    • Temporary weakness on one side of the body.
    • Brief inability to put words in the proper order, or difficulty finding the right words.
