title: Comorbidity of fibromyalgia and cervical myofascial  pain syndrome.
abstract: The aims of this study are to determine the frequency of fibromyalgia syndrome (FMS) in patients with chronic cervical myofascial pain (CMP) and to investigate the FMS characteristics in CMP patients. Ninty-three patients with CMP and 30 age-matched healthy women were included in this study. Main outcome measures included visual analog scale (VAS), Beck Depression Inventory (BDI), and pain pressure thresholds. CMP patients were evaluated for the existence of FMS. The severity of FMS was assessed with total myalgic score (TMS) and control point score (CPS). Most common clinical characteristics of FMS were noted. Of the 93 CMP subjects, 22 (23.6%) patients fulfilled the classification criteria for FMS. Number of tender points were higher (p=0.0), while TMS (p=0.0) and CPS (p=0.0) values were lower in comorbid CMP and FMS patients than regional CMP group. There were statistically significant differences between regional CMP patients and comorbid CMP and FMS patients regarding presence of fatigue (p=0.0) and irritable bowel syndrome (p=0.022). There was no statistically significant difference between patient groups regarding VAS values (p>0.05). BDI values of the regional CMP were significantly lower than comorbid CMP and FMS patients (p=0.011). In conclusion, we found that nearly a quarter of CMP patients were comorbid with FMS, and psychological and comorbid symptoms were more prominent in comorbid patients. We thought that, these two syndromes might be overlapping conditions and as a peripheral pain generator or inducer of central sensitisation, MPS might lead to FMS or precipitate and worsen the FMS symptoms.
