Fibromyalgia is a condition that causes pain, fatigue, and tender points around the body. It can be hard to diagnose because many of its symptoms are similar to those of other conditions. It can also be hard to treat. That's why it's important to see a doctor who has experience treating fibromyalgia.An estimated 5 million American adults - most of them women - have fibromyalgia, according to the National Institutes of Health (NIH).Eating a balanced diet is a good idea for anyone, regardless of whether you have fibromyalgia. That diet should include fresh fruits and vegetables, whole grains, healthy fats, low-fat dairy, and lean protein, such as chicken or fish. Avoid unhealthy foods, including anything processed or fried, and excessive amounts of saturated fats. Also, limit the amount of salt and sugar in your diet.
