Chronic widespread pain is the most common and well-known symptom. However, further research has found that people with FM also experience a myriad of symptoms, such as:
Diagnosis is based upon a thorough clinical evaluation from a healthcare provider. Currently, there are no tests for diagnosing FM. Since the symptoms of FM can also be caused by many other health conditions, other causes must be ruled out. It is a diagnosis of exclusion. 
FM is typically treated with a combination of lifestyle changes and pharmacological interventions. 
Lifestyle changes that may be implemented include:
- Improving sleep
- Gradually increasing physical activity
- Stress management
- Dietary changes
- Cognitive behavioral therapy
Medications that may be prescribed include:
- Muscle relaxants
- Medical cannabis
The treatment must be tailored to the individual's responses to any of the previously mentioned interventions.
Some studies found that dietary changes can improve symptoms of FM. However, the quality of these studies was poor and varied in their dietary interventions. More randomized controlled trials are needed to understand the relationship between diet and FM.
Since there are no standard treatments for FM, dietary supplements are often used to ameliorate symptoms. The supplements with the greatest amount of research are vitamin-d and coenzyme-q10. With that being said, the findings are inconsistent and more evidence is needed before recommendations can be made.
If initial therapies are not effective, people with FM may pursue alternative treatments to reduce symptoms. These treatments include:
The evidence surrounding these interventions is scarce. Therefore, it is recommended to consult a healthcare professional before implementing any alternative treatments.
