Tension headaches are usually located over the entire head, feel like a band and are often associated with tense neck muscles. Migraine headaches are more likely to be located on one side, more severe and throbbing, and associated with nausea and vomiting plus sensitivity to light and sound. They often have aura (warning signs) such as mood changes and visual disruptions. Medications to help prevent migraines are plentiful and more likely to be successful than those for tension headaches. Early use of triptans during the mild phase of migraine is usually helpful. Rescue pain medication ranging from aspirin to narcotics are frequently necessary.
