Migraine aura are warning signals experienced prior to a migraine attack. They may occur with or without the subsequent pain of a migraine headache. These may include:
- Visual disturbances including seeing flashing lights, dark spots, or zigzag patterns
- numbness or a tingling sensation similar to pins & needles which usually starts in one of the hands and moves up the arm before affecting the face, lips and tongue
- Dizziness or a loss of balance
- Speech impairment
- In very rare cases, a loss of consciousness
