Previously called transformed migraine headaches, chronic migraine headaches are migraine headaches occurring more than 15 days per month. Most people who get them have had migraines for years, usually since their early teens or before. Daily chronic migraine headaches usually start for people during their 20s and 30s.
When chronic migraine headaches begin, you might notice that your headaches are less severe but happen more often, until they happen every day. This change may be linked to daily use of pain relievers. Some people with chronic migraine headaches have severe pain along with nausea and vomiting, much like other types of migraines. Often, it’s hard to tell the difference between tension headaches and chronic migraine headaches.
Because chronic migraine headaches are tough to diagnose, many people may get the wrong treatment. And because the headaches happen every day, many people tend to take too many pain relievers, both prescription and over-the-counter, using these drugs daily even when they don’t have a headache. This means the person could build up a tolerance to the drugs. Plus, taking a lot of pain relievers with caffeine can lead to medication overuse headaches.
