Migraine is not just a bad headache. Migraine is a neurological disease with extremely incapacitating neurological symptoms. It’s typically a severe throbbing recurring pain, usually on one side of the head. In some cases, other disabling symptoms are present without head pain. Attacks are often accompanied by one or more of the following disabling symptoms: visual disturbances, nausea, vomiting, dizziness, extreme sensitivity to sound, light, touch and smell, and tingling or numbness in the extremities or face.
