Fibromyalgia
Five Years Later
This study investigated
the significance and course of pain in a female population over a period of
5.5 years. 2,038 women from the general population were evaluated for their
self-reported pain, history, and associated symptoms (fatigue, swelling, sleep
disturbance, waking achy). 1,168 reported chronic pain, and 214 had an extensive
interview and examination. 16 pain sites, and 18 tender points were examined
by applying pressure with fingers. The authors also measured the intensity
of fatigue, pain, and stiffness via a scale questionnaire.
In performing this study
the authors established four categories for pain and patients:
- Non Chronic Pain (NCP)
- Chronic Regional Pain
(CRP)
- Chronic Multifocal
Pain (CMP)
- Chronic Widespread
Pain (CWP)
At the baseline, 46 had
NCP, 69 CRP, 42 CMP, and 57 CWP. Of the 57 CWP, 39 patients met the diagnostic
criteria for fibromyalgia (FM).
5.5 years later only 7
patients had no pain. The regional pain group decreased by 11%, and the widespread
pain group increased by 11%. The FM subgroup increased to include 71 patients-33%
of the total sample. The following charts express the differences, and how
the groups changed over the years.

The authors conclude:
"These observations
indicate that the extension of pain in musculoskeletal pain syndromes tends
to increase with time, and that an evolution into widespread pain is not uncommon…These
findings, together with the overall increase in CWP, indicate an unfavorable
outcome of chronic pain, especially if the extension exceeds regional pain."
Furthermore, the authors
state that their "findings substantiate other reports…and indicate that FM
is a clinical syndrome at the severe end of a continuum rather than a well-defined
disease entity."
