Fibromyalgia and Widespread Pain: A Broader Workup

Summary

Dr. Jason W. Siefferman explains why a fibromyalgia label should not conclude a medical evaluation for widespread pain. While central sensitization explains how the nervous system amplifies pain signals, the label itself does not reveal why the sensitization occurred. Widespread aching can stem from undetected joint hypermobility, seronegative autoimmune inflammation, small fiber neuropathy, or autonomic dysfunction. Identifying these physical drivers requires examining symptom patterns across the connective tissue, nerves, and immune system rather than stopping at a descriptive category.

Conditions and treatments discussed

• Fibromyalgia. The diagnosis describes central sensitization and signal amplification, but it does not explain the underlying cause of the nervous system reactivity.
• Joint Hypermobility. Ligament laxity forces surrounding muscles to contract continuously to stabilize joints, generating widespread fatigue, muscle spasms, and persistent aching.
• Seronegative Autoimmune Disease. Inflammatory disorders can drive widespread symptoms without displaying clear markers on routine blood tests, presenting instead with enthesitis or morning stiffness.
• Small Fiber Neuropathy. Small nerve fiber damage produces burning, hypersensitivity, and migrating pain that standard neurological testing may fail to detect.
• Diagnostic Reevaluation. Evaluating widespread pain requires testing across joints, nerves, and the immune system to uncover specific drivers behind central sensitization.

What this shows about Manhattan Pain Medicine

Manhattan Pain Medicine describes a diagnosis-first framework centered on diagnostic reconsideration rather than accepting descriptive labels. In this article, Dr. Siefferman argues that a fibromyalgia diagnosis identifies central sensitization without uncovering what initiated the nervous system response. The practice reports investigating layered contributors, such as joint hypermobility or small fiber neuropathy, through detailed cross-system testing. By investigating mechanical, inflammatory, and neurological factors, Manhattan Pain Medicine focuses on identifying the specific drivers that keep pain amplified.
