Vaginismus and pelvic pain conditions

Vaginismus

Involuntary contraction of the pelvic floor muscles that prevents or obstructs vaginal penetration. It is a reflex, not a decision, and it is not evidence of unwillingness. Attempts at penetration typically produce burning, tearing sensation, or the experience of hitting a wall.

DSM-5 merged vaginismus and dyspareunia into genito-pelvic pain/penetration disorder, on the basis that they overlap heavily and are rarely cleanly separable in practice. Clinicians still use both older terms.

Lifelong vaginismus has been present from the first attempt at penetration. Acquired vaginismus develops after a period without difficulty and usually follows something identifiable: a painful infection, childbirth trauma, surgery, endometriosis, menopause-related dryness, or a frightening or coerced sexual experience. In both, a self-reinforcing cycle establishes itself — pain leads to anticipatory anxiety, anxiety leads to muscle guarding, guarding causes pain.

Treatment that works

Trial evidence supports a combined approach, and success rates in structured programmes are high.

• Graded dilator therapy. Starting with the smallest size, entirely self-inserted and self-paced, progressing only when the current size is comfortable. Self-insertion is not incidental — control is the mechanism.
• Pelvic floor physiotherapy. Downtraining, breathing, internal manual release, and biofeedback to learn what relaxation feels like.
• Cognitive behavioural therapy, particularly therapist-aided exposure. ter Kuile et al.'s randomised trial found high rates of successful intercourse after a brief exposure-based programme.
• Treating any underlying cause: infection, atrophy, lichen sclerosus, endometriosis.
• Topical anaesthetic as a short-term adjunct in some protocols, though it treats the symptom rather than the reflex.
• Botulinum toxin injection into the pelvic floor in refractory cases, with supportive but lower-quality evidence.

What does not work and causes harm: being told to relax, being told to drink wine, pushing through the pain, and a partner persisting past the point of pain. Repeated painful penetration reinforces the reflex and lengthens treatment.

Vulvodynia and provoked vestibulodynia

Persistent vulval pain of at least three months without an identifiable cause. Provoked vestibulodynia is the most common subtype: burning at the vestibule triggered by touch, tampon insertion, speculum examination or attempted penetration.

It is not psychosomatic. Biopsy studies have found increased nerve fibre density in the vestibule of affected people, and quantitative sensory testing shows evidence of both peripheral and central sensitisation.

Management is multimodal and takes months: pelvic floor physiotherapy, topical treatments including compounded amitriptyline or oestrogen, oral tricyclics or gabapentinoids, cognitive behavioural therapy, and — in carefully selected refractory cases with localised provoked pain — vestibulectomy, which has good outcomes in appropriate candidates.

Other pelvic pain conditions

Interstitial cystitis / bladder pain syndrome. Bladder pain, urgency and frequency without infection. Frequently coexists with pelvic floor hypertonicity; Fitzgerald et al.'s randomised trial (2012, Journal of Urology) found myofascial physical therapy significantly more effective than global massage.

Pudendal neuralgia. Burning, shooting or aching pain in the pudendal nerve distribution, typically worse sitting and better standing or lying. Frequently misdiagnosed for years. Diagnosis uses the Nantes criteria; treatment includes physiotherapy, nerve blocks and, rarely, decompression surgery.

Chronic pelvic pain syndrome in men (chronic non-bacterial prostatitis). Common, frequently treated with repeated antibiotic courses that do not help. Anderson et al. demonstrated benefit from myofascial trigger point release combined with relaxation training. A pelvic floor assessment should come before a third antibiotic course.

Coccydynia, hip impingement, and myofascial pain in the abdominal wall and adductors all refer into the pelvis and are missed when assessment stops at the reproductive organs.

Central sensitisation

Long-standing pelvic pain frequently coexists with fibromyalgia, irritable bowel syndrome, migraine, temporomandibular disorder and chronic fatigue. The shared mechanism is central sensitisation — the nervous system amplifying pain signals. This has treatment implications: pain neuroscience education, graded exposure, sleep and stress management, and centrally acting medication such as tricyclics or duloxetine, rather than escalating searches for local pathology alone.

It also means the pain is real even when investigation finds nothing. "Nothing on the scan" is not "nothing wrong".

Getting care

Ask for referral to a pelvic health physiotherapist and, where available, a specialist vulval or pelvic pain clinic. Bring a written symptom record: location, quality, triggers, timing, cycle relationship, bowel and bladder symptoms, and everything already tried. Persistence is frequently required, and it should not be.
