Stat of the Week
Throbbing pain, often just on one side of the head. Sensitivity to noise and light. Nausea or vomiting. Foggy thinking, exhaustion. These are common symptoms of migraine headaches, which affect millions of people. Much more than just a bad headache, a migraine can last hours or days.
Research shows certain biofeedback techniques successfully reduce migraine frequency and severity, without side effects if used alone. Biofeedback also may be useful when combined with medication.
