There are no specific tests that can confirm a diagnosis of fibromyalgia. You will likely have lab tests to make sure that you don't have another condition causing your symptoms. Your doctor will also ask questions about your medical history and do a physical exam.
Doctors use a set of criteria to diagnose fibromyalgia. These include:
- Widespread pain. Pain is considered to be widespread if it is above and below your waist and on the right and left sides of your body.
- Other symptoms such as fatigue, trouble sleeping or feeling unrefreshed in the morning, and trouble thinking. If these symptoms are severe, widespread pain may not be as important in the diagnosis.
- Symptoms that have lasted for at least 3 months.
- No other medical explanation for why you feel this way (for example, another health condition or disease).
A person may not meet these criteria but may still have fibromyalgia. That is why diagnosis can be so difficult.
