Vulvodynia/Vestibulodynia

About

  • Chronic vulvar pain with an unknown cause
  • The location and severity of pain can vary among sufferers
  • Some women will experience pain in one area of the vulva, while others will experience pain in multiple areas
  • 2 main subtypes
    • Localized Vulvodynia: Pain experienced at only one vulvar site
      • Provoked Vestibulodynia (PVD): Pain limited to the vestibule occurring before/after pressure is applied to the vestibule ie: sexual intercourse, gynecologic exams, tampon insertion, sitting for extended periods of time, wearing tight pants
      • Vestibulodynia: Pain in the vestibule (the tissue surrounding the vaginal opening)
      • Clitorodynia: Pain in the clitoris, less common form of localized vulvodynia
    • Generalized Vulvodynia
      • Pain can occur spontaneously and can be fairly constant, although there can be periods of relief from symptoms
      • Activities that apply pressure to the vulva can often make symptoms worse ie: sexual intercourse, sitting for extended periods of time, wearing tight pants
      • Some women may experience pain in a specific area while others can experience pain in multiple areas even including the perineum and inner thighs

Potential Causes

  • Researchers speculate that one or more of the following may cause/contribute to the condition:
    • Pelvic floor dysfunction
    • Past vaginal infections
    • Allergies/sensitive skin
    • Hormonal changes
    • Injury/irritation of the nerves surrounding the vulvar region
    • Increase in sensitivity of pain-sensing nerve fibres in the vulva
    • Abnormal vulvar cell response to environmental factors such as infection/trauma
    • Genetic susceptibility to chronic vestibular inflammation, chronic widespread pain and/or inability to fight infection

Symptoms

  • Pain/burning near the opening of the vagina, and sometimes only when something touches that area
  • Pain on/around the vulva, even when nothing touches that area
  • Burning/Stinging
  • Itching
  • Swelling
  • Throbbing
  • Rawness
  • Painful intercourse (dyspareunia)
  • Flares up during and after sexual intercourse, wiping, sitting on a bicycle or inserting a tampon

Diagnosis

  • Medical, sexual and surgical history and symptom evaluation 
  • Vaginal exam: Vulva, vagina and vaginal secretions are checked to rule out an infection/skin disorder
  • Blood test: To assess hormone levels
  • Cotton-swab test: To gently check for specific, localized areas of pain in your vulvar region

Treatment

  • Oral Medications:
    • Pain medications: Steroids, tricyclic antidepressants, anticonvulsants
    • Antihistamines: To reduce itching
  • Topical Medications
    • Hormonal creams 
    • Local anaesthetics: Lidocaine 
    • Compounded formulations 
  • Discontinuation of irritants (ie: laundry detergent, soaps, etc)
  • Pelvic Floor Physiotherapy
  • Biofeedback Therapy:  Teaching you how to relax your pelvic muscles and control how your body responds to the symptoms
  • Nerve Blocks
  • Surgery: To remove the affected skin and tissue (vestibulectomy) in cases of localized vulvodynia or vestibulodynia
