Persistent Vulvar Pain
/Reading: Committee Opinion No. 673 - Persistent Vulvar Pain
What is persistent vulvar pain?
- Persistent vulvar pain is a complex disorder and often very frustrating to both the patient and the provider 
- Because it is difficult to treat and even with appropriate treatment, pain may not resolve completely 
- Terminology and Classification - from 2015 Consensus Terminology and Classification of Persistent Vulvar Pain 
- From the International Society for Study of Vulvovaginal Disease: 
- Can be caused by a specific disorder or it can be idiopathic 
- Idiopathic vulvar pain = vulvodynia 
- Vulvar pain caused by specific disorder: 
- Infectious (ie. recurrent candidiasis, herpes) 
- Inflammatory (lichen sclerosus, lichen planus, etc.) 
- Neoplastic (ie. Paget disease, SCC) 
- Neurologic (postherpetic neuralgia, nerve compress or injury) 
- Trauma 
- Iatrogenic (postoperative, chemotherapy, radiation) 
- Hormonal deficiencies (ie. genitourinary syndrome of menopause, lactational amenorrhea) 
- Vulvodynia = vulvar discomfort, most often reported as burning pain, which occurs in the absence of relevant visible findings or a specific, clinically identifiable neurological disorder for at least 3 months 
- Descriptors 
- Localized (ie. vestibulodynia, clitorodynia), general, or mixed (can be localized or generalized) 
- Provoked (ie. insertional, contact), spontaneous, or mixed (provoked and spontaneous) 
- Onset (primary or secondary) 
- Temporal pattern (intermittent, persistent, constant, immediate, delay) 
How do we evaluate what the cause of vulvar pain is?
- Exclude other causes before assigning vulvodynia 
- Vulvodynia = diagnosis of exclusion 
- History 
- Do your normal OPQRS – how long has the patient been having pain? Where is it? 
- Also obtain medical and surgical history 
- Sexual history - make sure to ask permission 
- Allergies 
- Previous treatment 
- Physical exam 
- Know your anatomy! 
- Cotton swab test - Using a cotton swab and moving across the labia → start on thighs → labia majora → interlabial sulci. Then test vestibule in the 2, 4, 6, 8, 10 o’clock position 
 
- R/o infection 
- Wet mount, vaginal pH, fungal culture, and gram stain 
- Vulvoscopy - usually not needed 
- If there is concern, you can also biopsy an area - can find dermatoses 
- Musculoskeletal evaluation 
- Palpation of the different muscles within the pelvis to see if there is referred pain 
- Palpation of the pubovaginalis portion of the levator ani, obturator internus, and urethrovaginal sphincter 
Treatment
- Unfortunately, the evidence for treating vulvodynia is based on clinical experience and observational studies - few randomized studies exist 
- If there is obvious cutaneous or mucosal disease present 
- Treat the disease! Ie. infections, dermatoses 
- We talk about this here on previous podcasts: 
- If there is not, do the cotton swab test 
- If no areas of tenderness then consider alternative diagnosis 
- If there is tenderness or burning with cotton swab test, do a yeast culture 
- Positive yeast culture: antifungal 
- If negative, or if antifungal does not provide adequate relief, move to: 
- Vulvar care measures 
- Cotton underwear and no underwear at night 
- Avoid vulvar irritants and douching 
- Mild soaps for bathing, or anti-allergenic soaps, do not apply directly to vulva 
- Apply preservative free emollient (ie. coconut oil) 
- Switch to 100% cotton menstrual pads 
- Use water based lube for intercourse 
- Cool gel to vulvar area for relief 
- Topical medications - ie. estrogen cream, tricyclic antidepressants can be compounded 
- Oral medications - TCAs and anticonvulsants; use one drug at a time 
- TCAs should be used for up to 3 weeks to assess adequate pain control 
- Injections (ie. botox for trigger point injections, can also use steroids for trigger point injections ) 
- Biofeedback/physical therapy - assess for pelvic floor dysfunction 
- Dietary modification 
- CBT 
- Sexual counseling 
- If still no adequate relief and localized pain → can consider surgery with vestibulectomy 
- Should only be done if other treatments have failed 
- Success rate is 60-90% compared to 40-80% for nonsurgical interventions 
- If generalized pain - consider increasing the dose of medication, combining meds, etc.
