Vulvodynia

Vulvodynia - Ouch Origins

• Chronic vulvar pain (≥ 3 months) without identifiable cause; diagnosis of exclusion.
• Prevalence: Affects up to 16% of women.
• Classification (ISSVD 2015):
  • Localized: e.g., Vestibulodynia (most common), clitorodynia.
  • Generalized: Diffuse vulvar pain.
  • Provoked: Triggered by touch/pressure (e.g., intercourse, tampon insertion).
  • Spontaneous: Occurs without a clear trigger.
  • Mixed: Both provoked and spontaneous elements.

⭐ Vestibulodynia, particularly provoked, is the most frequently reported subtype of vulvodynia, often presenting as insertional dyspareunia.

📌 Vulvar Pain Syndrome: Vestibulodynia Predominates Significantly

Vulvodynia - Mystery Malady

• Chronic vulvar pain (burning, stinging, rawness) >3 months, without an identifiable cause.
• Types:
  • Generalized: Spontaneous, diffuse.
  • Localized: Provoked, unprovoked, or mixed.
    • Vestibulodynia: Pain localized to vestibule.

      ⭐ Provoked vestibulodynia (PVD), pain on touch at the vestibule, is the most common subtype of vulvodynia.

• Etiology: Multifactorial - neuropathic, inflammatory, hormonal, musculoskeletal, genetic.
• Diagnosis: Exclusion; Q-tip test for localized tenderness.
• Management: Multimodal - topical (lidocaine), oral (TCAs), pelvic floor PT.

Vulvodynia - Pain Portrait

• Chronic vulvar discomfort, often described as burning, stinging, irritation, or rawness.
• Pain can be generalized or localized (e.g., vestibulodynia, clitorodynia).
• Provoked (e.g., by touch, intercourse - dyspareunia) or unprovoked, or mixed.
• Symptoms must persist for at least 3 months.
• No visible dermatological or neurological disorder.

⭐ Vestibulodynia (provoked, localized) is the most common subtype, with pain typically at the posterior fourchette during vaginal entry or pressure.

Vulvodynia - Detective Work

• History Taking:
  • Pain: Onset, duration, quality (burning, raw), triggers (touch, intercourse).
  • Location: Localized (e.g., vestibulodynia) vs. generalized.
  • Impact: Sexual function, quality of life.
• Clinical Examination:
  • Visual inspection: Erythema, fissures, atrophy. Exclude visible lesions.
  • Q-tip Test: Gentle pressure to map tender areas (vestibule, clitoris, perineum). Record pain score (0-10).

    ⭐ The cotton swab (Q-tip) test is crucial for localizing pain and differentiating generalized vs. localized, provoked vs. unprovoked vulvodynia.

• Investigations:
  • Rule out infections: Vaginal swabs (wet mount, pH, cultures for Candida, BV).
  • Biopsy: If lesions, diagnostic uncertainty, or to exclude dermatoses (lichen sclerosus/planus).
  • Consider: Neurological assessment if indicated.

Vulvodynia - Relief Roadmap

• Initial Steps (Conservative):
  • Vulvar care: gentle cleansing, loose cotton clothing, avoid irritants (soaps, douches).
  • Topical relief: Lidocaine 5% ointment for temporary anesthesia; topical estrogens for atrophy.
• Pharmacotherapy (Neuropathic Pain Focus):
  • Oral agents: TCAs (e.g., Amitriptyline 10-25mg nightly, titrate up), SNRIs (Duloxetine), Anticonvulsants (Gabapentin, Pregabalin).
• Multimodal Approach:
  • Pelvic floor physical therapy: biofeedback, myofascial release.
  • Psychological support: Cognitive Behavioral Therapy (CBT), counseling.
  • Nerve blocks (e.g., pudendal).
• Surgical Intervention (Last Resort):
  • Vestibulectomy for localized, provoked vestibulodynia.

⭐ A multimodal approach combining pharmacotherapy, physical therapy, and psychological support is often most effective for managing vulvodynia.

High‑Yield Points - ⚡ Biggest Takeaways

• Vulvodynia: Chronic vulvar pain (≥3 months) without identifiable cause; diagnosis of exclusion.
• Commonest: Localized provoked vulvodynia (LPV), pain on touch, often at vestibule.
• Q-tip test (cotton swab) is crucial for diagnosis, localizing pain.
• Exclude: Infections (Candida, HSV), dermatoses (lichen sclerosus/planus), neurological disorders.
• Treatment: Multimodal - topical lidocaine, pelvic floor PT, TCAs (amitriptyline), gabapentin.
• Vestibulectomy: Surgery for refractory LPV.
• Address associated psychosocial distress and sexual dysfunction.
