Many people with fibromyalgia say they also suffer from frequent headaches and/or migraines. It's important to note that headaches and migraines are two very different things. A migraine is not just a really bad headache. It is a genetic neurological disease that is characterized by flare-ups, which are called migraine attacks. While head pain is common with migraines, it is possible to have a migraine attack without having a headache.
Like FM, migraine disease seems to be a central nervous system problem that results in hypersensitivity to various triggers. There are many theories as to exactly what happens to bring on a migraine attack, but the most prevalent theory is that people with migraines have overly excitable neurons in their brains. When they encounter a trigger, those neurons fire in a wave across the brain, starting a cascade of events involving several parts of the brain.
The most common type of headache is the tension-type headache. These headaches usually occur on both sides of the head and have a pressing or tightening quality to them. Some patients describe them as feeling like they have a tight band around their head. Since pain in general tends to cause the body to become tense, it's not surprising that people with fibromyalgia might develop tension-type headaches.
One type of headache that is important to mention, especially for FM patients, is the rebound or medication-overuse headache. It is caused by the very medication being taken to relieve the pain. Unfortunately, people who are susceptible to rebound headaches find themselves in a catch-22 situation. In these cases, when patients take medication to relieve the headache or migraine pain more than two or three times a week, their bodies get used to having the medication and actually create a headache in order to get more of the medication. The only way to break this cycle is to stop taking the medication that caused it. This can be a particularly difficult problem for people with fibromyalgia since often the medications being taken to relieve FM pain can cause rebound headaches.
