Viscero-visceral hyperalgesia in dysmenorrhea plus previous urinary calculosis: role of myofascial trigger points and their injection treatment in the referred area.


Women with dysmenorrhea plus symptomatic urinary calculosis experience enhanced pain and referred muscle hyperalgesia from both conditions than women with one condition only (viscero-visceral hyperalgesia). The study aimed at verifying if enhanced dysmenorrhea persists after urinary stone elimination in comorbid women and if local anesthetic inactivation of myofascial trigger points (TrPs) in the lumbar area (of urinary pain referral) also relieves dysmenorrhea.
