Do you have a headache?
You are not alone. Most everyone suffers from one at one point. Most of the time, symptoms can be alleviated at home. Sometimes, the pain requires specialized treatment or emergency care. Migraine headaches can last a day or more and can strike as often as several times a week or as rarely as once every few years. Keep in mind there are preventive behavioral steps and medicines that can help manage headaches.
