Migraine headaches can literally bring your existence to a halt. Anybody who has ever experienced the discomfort triggered by a migraine will completely understand this statement. Often involving only a single side from the head, these headaches could be very debilitating for that sufferer. They are able to make you nauseous, and even be painful towards the point that you simply vomit. Episodes can last from 12 to 72 hours, with small or no relief.
