People with migraine may experience symptoms up to 72 hours (three days) before the headache starts, such as difficulty concentrating, mood changes, nasal congestion, runny nose, eyes tearing and changes in thirst and appetite.
Migraine can usually last from a few hours to a few days, and can include pulsating headaches of moderate to severe pain intensity that can be associated with nausea or vomiting, and/or sensitivity to sound and light.
While most sufferers experience attacks once or twice a month, it is estimated that one to four percent of the U.S. population have Chronic Migraine, with at least 15 headache days per month and with eight or more migraine days per month.
Prevalence & Impact
Location: The pain of migraine is generally on one side of the head and feels pounding or pulsating.
Effects: There may be sensitivity to light, sound, smells, and touch. Nausea and vomiting are common.
Aura experience: This is a neurologic symptom, such as seeing flashing lights or experiencing blind spots in the vision, feeling pins and needles in the limbs, or having difficulty talking. The aura generally occurs before the start of the migraine but can occur during it.
When the migraine is over, a person may experience a feeling of fatigue or overall lethargy that can last up to a day.
