Does fibromyalgia show on a nerve test?

Answered by Willie Powers

Fibromyalgia is a complex condition that is characterized by widespread pain, fatigue, sleep disturbances, and other symptoms. It is a diagnosis of exclusion, meaning that other potential causes of the symptoms must be ruled out before a fibromyalgia diagnosis can be made. Nerve function tests are one of the medical tests that may be ordered during the diagnostic process.

Nerve function tests, also known as nerve conduction studies, are used to evaluate the function of the nerves in the body. These tests can help to detect abnormalities in nerve function, such as nerve damage or compression. However, it is important to note that nerve function tests are not specific for fibromyalgia and cannot definitively diagnose the condition.

In fibromyalgia, there is no specific nerve damage or compression that can be detected through nerve function tests. Instead, the pain in fibromyalgia is believed to be related to abnormal processing of pain signals in the central nervous system. This means that the nerves themselves are not necessarily damaged, but rather there is a problem with how the brain and spinal cord interpret and respond to pain signals.

That being said, nerve function tests may still be ordered as part of the diagnostic process for fibromyalgia. This is because there are other health conditions that can cause similar symptoms to fibromyalgia, and these conditions may be detectable through nerve function tests. Some examples of conditions that may be ruled out include peripheral neuropathy, radiculopathy, and other nerve-related disorders.

Blood and lab tests may also be ordered to help rule out other potential causes of the symptoms. These tests can check for markers of inflammation, thyroid function, vitamin and mineral deficiencies, and other abnormalities that may be contributing to the symptoms.

Imaging studies, such as X-rays or MRI scans, may be used to rule out other conditions that can cause similar symptoms, such as arthritis or spinal disc problems. These tests can help to visualize the structure of the bones, joints, and soft tissues, and can sometimes identify abnormalities that may be contributing to the pain and other symptoms.

While nerve function tests are not specific for fibromyalgia, they may still be ordered as part of the diagnostic process to help rule out other conditions that can cause similar symptoms. A diagnosis of fibromyalgia is typically made based on a combination of characteristic symptoms, a physical examination, and ruling out other potential causes. It is important to work with a healthcare professional to determine the most appropriate tests and diagnostic approach for your individual situation.
