Provoked vestibulodynia (PVD) is a chronic pain condition of the vulva, diagnosed by eliciting pain on the vestibule, “the cotton-swab test.” Fibromyalgia (FM) is a chronic musculoskeletal pain condition, diagnosed by eliciting pain with pressure on 11 out of 18 defined tender points (TPT). Both conditions are of unknown etiology. Fibromyalgia has been recognized as a co-morbidity of vulvodynia but the number of women with PVD who have fibromyalgia is not clear. Our objectives were: to determine the prevalence of FM, diagnosed by TPT exam, in women with PVD. 2. To compare the prevalence of FM by TPT with the reported prevalence of personal or family history (FH) in the same women.METHODS:
Women aged 18 or older diagnosed with PVD were screened for FM with a TPT examination. Medical history, collected prior to examination, was reviewed to determine reported prevalence of personal or FH of FM.RESULTS:
All 147 women enrolled in the study underwent TPT evaluation. Twenty six women screened positive for fibromyalgia, prevalence of 17.7%. Of the 143 women with a completed medical history, 12 had a personal or FH of FM, prevalence 8.4%.CONCLUSION:
Women with PVD had a higher prevalence of FM by TPT than that which is reported in the general population (17.7% vs 2–6.4%), and a higher prevalence of FM by TPT than would be expected by personal and FH (17.7% vs 8.4%). Future studies may determine if treatment of co-morbidities improves outcomes in this population.
