Latent class analysis of comorbidity patterns among women with generalized and localized vulvodynia: preliminary findings

Journal of pain research ·doi:10.2147/JPR.S42940

BACKGROUND: The pattern and extent of clustering of comorbid pain conditions with vulvodynia is largely unknown. However, elucidating such patterns may improve our understanding of the underlying mechanisms involved in these common causes o…

Co-morbid pain conditions and feelings of invalidation and isolation among women with vulvodynia

Psychology, health & medicine ·doi:10.1080/13548506.2011.647703

Many women with vulvodynia also suffer from other chronic co-morbid pain conditions. Alone, these pain conditions are associated with feeling invalidated by others and feeling socially isolated. It is unclear, however, how the presence of a…
