What to do if i get a lot of headaches and it freaks me out?

Find out why: Perhaps you have chronic daily headaches due to tension cephalgia or migraine, and these may be now a reaction to pain killers used recently. Consider underlying problems such as neck or TMJ pain generators, but very unlikely your problem due to an expanding brain tumor. Regardless, there are medicines to break up these kind of patterns and please see you doctor and address this.

Identify triggers: There are certain foods and aspects of lifestyle that can trigger or worsen headaches and migraines. The best way to identify triggers is to maintain a headache diary and keep a list of foods eaten before your migraine. Common triggers include chocolate, caffeine, cheese, msg, processed meats, alcohol, smoking/being around smoke, stress, skipping meals, lack of sleep or too much sleep.
