A migraine is not just a headache. Migraines are usually more severe and last longer than headaches. Migraines can last as long as 72 hours.
The major symptom of a migraine is pain that you usually feel on one side of your head. This pain is typically moderate or severe. Migraines also include other symptoms, such as nausea, vomiting, and severe sensitivity to light and sound.
About 20% of people who have migraines experience an aura before the pain begins. An aura is a group of symptoms. You could have some or all of the following symptoms during a migraine aura:
- Changes in your vision, such as seeing squiggly lines or having short-term, partial vision loss
- Difficulty talking
- Tingling or numbness of any part of your body
It is not known exactly why people have migraines. However, some people can track their migraine back to a certain trigger. Migraine triggers can include stress, lack of sleep, certain foods, and even hormone changes during a menstrual cycle.
Some people can prevent migraines by avoiding triggers. Others have prevented migraines successfully through relaxation techniques, acupuncture, or exercise. However, these therapies alone don’t work for everyone. Some people also need treatment with medication to reduce the number of migraines they have. The drugs used to prevent migraines are different from drugs that to treat migraines once a migraine starts. Drugs that prevent migraines, such as gabapentin, must be taken on an ongoing basis to work properly.
Gabapentin is a drug that is approved to treat seizures in people with epilepsy. It is also approved to treat nerve pain from shingles, which is a painful rash caused by herpes zoster infection. It’s used off-label for migraine prevention.
Gabapentin belongs to a class of drugs called anticonvulsants. A class of drugs is a group of medications that work in a similar way. Anticonvulsants help calm nerve impulses. It is believed that this action can help prevent migraine pain.
