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.
