There is no lab test or imaging scan that can identify fibromyalgia. These tests may be used by your healthcare professional to rule out other possible reasons of your persistent pain. You can learn some of the ways in which doctors diagnose and treat this condition below: In order to make a diagnosis of fibromyalgia, your doctor will take your history and do a physical examination. There are several blood tests and imaging scans that can be done as well. Your doctor may also ask you to complete questionnaires about your symptoms. This allows them to compare your responses with other people's reports and come up with an accurate diagnosis. Your doctor will likely start by asking you about your history of pain. He or she will want to know if your pain is constant or not. If it is constant, then you should be examined for other conditions that cause constant pain such as arthritis or cancer. If the pain does not go away even with treatment, then fibromyalgia may be the reason for your pain. During the history taking process, your doctor will also want to know about any other symptoms that you have, including fatigue, headaches, memory problems, depression, and anxiety.
