Fibromyalgia, chronic fatigue syndrome, and myofascial pain syndrome.
Goldenberg, D L · Current opinion in rheumatology · 1995 · DOI
Quick Summary
This review article examines fibromyalgia, chronic fatigue syndrome, and related muscle pain conditions. Research using specialized magnetic imaging showed that muscle damage is not the main problem in fibromyalgia. Scientists are now focusing on how the brain and nervous system may be involved in these conditions, using new technologies to better understand what causes them.
Why It Matters
This early perspective helped redirect ME/CFS research away from peripheral muscle abnormalities toward central nervous system dysfunction, establishing a more accurate foundation for future investigations. The recognition that muscle is not the primary problem validated patients' experiences while opening new avenues for targeted research and potential treatments.
Observed Findings
Nuclear magnetic resonance spectroscopy studies found no primary muscle pathology in fibromyalgia
Tricyclic medications showed modest initial therapeutic benefit in fibromyalgia
Tricyclic medication efficacy was not sustained at 6-month follow-up
Fibromyalgia and ME/CFS may follow or mimic Lyme disease in some patients
Inferred Conclusions
Muscle tissue is not the primary site of dysfunction in fibromyalgia
Central nervous system involvement is likely fundamental to fibromyalgia and ME/CFS pathology
Advanced neuroimaging and neurohormonal assessment technologies are needed to identify underlying mechanisms
Short-term medication effects do not necessarily translate to sustained clinical benefit
Remaining Questions
What are the specific central nervous system abnormalities in ME/CFS and fibromyalgia?
How do Lyme disease and ME/CFS/fibromyalgia relate mechanistically?
What neuroimaging and hormonal changes characterize these conditions?
What This Study Does Not Prove
This editorial does not prove what the primary cause of ME/CFS or fibromyalgia is—only that muscle damage is not it. The article does not establish efficacy or long-term safety of any specific treatments, and the association with Lyme disease requires further investigation to clarify causation versus coincidence.
