Stomach migraines usually start during childhood and start for no apparent reason. They can last for 2-3 hours but can cripple a person for up to three days. There is a lot of abdominal pain associated with stomach migraines and they can be accompanied by nausea and vomiting. Certain triggers, such as smells and light, can aggravate the condition.
The most common medication that doctors prescribe to treat stomach migraines is valporic acid. There are other medications available but this is the preferred one to use. It is also important to keep a food diary. If a particular food is causing the stomach migraine then it can be identified and avoided.
