• Visual disturbances about 30 minutes prior to getting a migraine. Migraine sufferers report visual disturbances such as an aura or halo, flashing lights, spots, and wavy lines. The visual disturbances are followed by a throbbing headache.
• Severe headache accompanied by a throbbing or pulsating sensation typically on one side of the head.
• Headache pain worsens with increased physical activity.
• Nausea, vomiting, or both.
• Light and/or noise hypersensitivity. Migraine sufferers may feel the need to retreat to a dark, quiet room for relief.

Diagnosis
The following tests and procedures may help you find out what is causing migraines:

• Online Self-assessments – Self-assessments, such as the Candidiasis Self-assessment and the Magnesium Assessment, can help you determine some of the root cause(s) of your chronic conditions. Learn more about Self-assessments.
• CT (computed tomography) scan – May be ordered to rule out brain disorders or headaches caused by chronic sinusitis.
• X-rays – May also be used if sinusitis is strongly suspected.
• A neck x-ray – Can reveal arthritis or spinal problems.
• Other tests  –  May include an MRI (magnetic resonance imaging), EEG (electroencephalogram), lumbar puncture, ultrasound testing, and cerebral angiography, which are only performed if there is reason to suspect an underlying disease.
