Fibromyalgia is a chronic medical condition that is characterised by widespread pain, fatigue, waking unrefreshed and cognitive disorders. The diagnostic criteria are subjective, and teh condition remains controversial in some circles due to this. Recent work has found that 40-50% of patients have small fibre neuropathy.
Epidemiology
Fibromyalgia is present across the world, and has a prevalence ranging between 2% to 4%.
Diagnosis
The current criteria for fibromyalgia were established in 2010 by the American College of Rheumatology (ACR). There is no requirement for a tender point examination like in the ACR 1990 classification. Three criteria must be met for the diagnosis
- Widespread Pain Index (WPI) ≥ 7/19 and Symptom Severity Scale (SSS) Score ≥ 5/12 or WPI between 3–6/19 and SSS ≥ 9/12
- Symptoms being present at a similar level for at least 3 months
- The patient does not have another disorder that would otherwise sufficiently explain the pain.
Conditions 1 and 2 are assessed by the Fibromyalgia Survey Questionnaire.
Small Fibre Neuropathy and Widespread Pain Syndromes
Oaklander et al found that in 41 patients with unexplained widespread pain that started before the age of 21, 59% of children at definite small fibre neuropathy (SFN), 17% had probable SFN, and 22% had possible SFN.[1] They then found that in a group of 27 fibromyalgia patients and 30 matched controls, 41% of fibromyalgia patients had definite SFN, compared to 3% in the control group.[2] Following this research in the early 2010s, there has been numerous further research in this area, which has reinforced that a proportion of fibromyalgia patients actually have SFN - a neuropathic pain syndrome. Overall it appears that around 40-50% of fibromyalgia patients have SFN.
