It is unproven exactly what causes “migraine attacks,” but scientists understand that it has to do with blood vessel contractions, various fluctuations in the brain, and inherited brain defects. A migraine attack occurs with or without head pain, and may include other symptoms:
- Severe nausea
- Stomach cramps
- Vomiting
- Diarrhea
- Eye pain
- Aura- stroke-like symptoms, including speech slurs, disorientation, temporary partial paralysis, visual and olfactory hallucinations, muscular feebleness, loss of consciousness
