What Is Vulvodynia and Why Does It So Often Go Undiagnosed?

A burning that arrives without warning, a rawness that makes sitting uncomfortable, a stinging that has no obvious cause and yet will not go away. If you have been living with pain in your vulval area and have struggled to describe it, or have been told that nothing looks wrong, vulvodynia is a chronic vulval pain condition that affects around 1 in 7 women at some point in their lives, yet it remains one of the most underdiagnosed conditions in women's health. The gap between when symptoms start and when a diagnosis arrives is often measured in years, not months.¹

What is vulvodynia?

Vulvodynia means chronic vulval pain lasting three months or more with no identifiable cause such as infection, skin condition, or nerve disorder. That last part matters: a diagnosis is reached after other causes have been ruled out, which is why seeing a GP is essential. Your doctor will consider and exclude infective causes such as thrush, herpes, and bacterial vaginosis, as well as skin conditions, before arriving at a vulvodynia diagnosis.²

Symptoms vary from person to person. You may notice burning, stinging, soreness, aching, or rawness. The pain can be constant, or it can be triggered by touch, pressure, or penetration. When it follows that triggered pattern, it is sometimes called provoked vestibulodynia.³

The exact cause is not fully understood. Possible contributing factors include nerve damage or irritation, the way vulval tissue responds to past infection or trauma, hormonal changes, and tension or dysfunction in the pelvic floor muscles. Because no single cause has been pinned down, the condition does not follow a predictable pattern, which is part of why getting a timely diagnosis can take so long.⁴

Vulvodynia and chronic pelvic pain

Vulvodynia often sits alongside chronic pelvic pain (CPP). Like vulvodynia, it affects relationships, mental health, and day-to-day life in ways that are significant, and it is frequently underdiagnosed and undertreated. If you are experiencing both vulval pain and broader pelvic pain, raising both with your GP will help ensure a fuller picture is looked at.⁵

Why vulvodynia pelvic pain so often goes unrecognised

Vulvodynia goes unrecognised for several overlapping reasons. The pain is located in an area that can feel difficult to describe or bring up. Symptoms may come and go, making them harder to track or report clearly. And there is a well-documented pattern in pain medicine of pelvic pain being put down to anxiety, relationship difficulties, or low pain tolerance, rather than being treated as a physical condition that warrants proper investigation. If a previous appointment felt dismissive, it is still worth going back. A symptom diary kept in the weeks before your appointment can be a useful tool.⁶

How your cycle may affect symptoms

Oestrogen and progesterone shift throughout your cycle, and those hormonal changes can influence how sensitive vulval tissue feels, how much natural lubrication you have, and how your body registers pain. You may find that symptoms feel worse at certain points in your cycle, particularly in the days before and during your period when oestrogen dips. This is not yet an established clinical finding, and the pattern varies considerably. If you do notice it, it is worth logging in your symptom diary and raising with your GP or specialist.⁸

Some studies have pointed to a possible link between low-dose combined oral contraceptives and vulvodynia starting or getting worse, which may be connected to a drop in local oestrogen levels. If you have concerns about your contraception and vulval symptoms, talk to your GP or a sexual health clinician. Do not stop or change your contraception based on this article.⁹

Pelvic floor physiotherapy as a management option

Tension or dysfunction in the pelvic floor muscles is common in people with vulvodynia and chronic pelvic pain. This can mean muscles that are overactive or persistently tight (a pattern called hypertonia), or difficulty coordinating them, either of which can contribute to pain or keep it going. Pelvic floor physiotherapy is recommended as a treatment for vulvodynia. A specialist physiotherapist can assess what is happening in your pelvic floor and work with you on approaches that may include manual therapy, biofeedback, and relaxation exercises.¹⁰

Your GP can refer you to a pelvic floor physiotherapist. Waiting times vary across the country, so it is worth asking what is available in your area and whether a referral to a specialist pain clinic or a multidisciplinary pelvic pain service would be appropriate.

Other treatments your GP or specialist may discuss

Treatment depends on the underlying cause, as vulvodynia can sometimes occur alongside other vulval conditions, which is why an accurate diagnosis from a specialist is the starting point for any treatment plan. Options your GP or specialist may prescribe or suggest include topical anaesthetics, topical oestrogen cream, and medications used for nerve pain such as certain antidepressants or anticonvulsants. These are decisions made with a prescriber and not treatments to seek independently. Cognitive behavioural therapy (CBT), a structured talking therapy that can help with the way chronic pain is processed and managed, is also used as part of a broader pain management approach. In a small number of cases, and only under specialist guidance, a surgical procedure called a vestibulectomy may be considered. Your GP or specialist will talk through what is most appropriate for your situation.¹¹

Supportive self-management measures

Alongside professional treatment, there are practical steps that may help to reduce irritation and discomfort day to day. These are supportive measures, not substitutes for medical care.

• Use unperfumed soaps and washing products in the vulval area
• Wear loose-fitting cotton underwear and avoid tight clothing
• Apply a cool gel pack wrapped in a cloth to the area to ease discomfort
• Use a vaginal lubricant during sex to reduce friction and pressure¹²

When to seek support

See your GP if you have persistent vulval pain or discomfort, particularly if it has been there for more than a few weeks or is affecting your daily life, sex, or mental health. New or unexplained symptoms always need a professional assessment. A symptom diary that records the type of pain, where it is, when it happens, and any possible triggers will give your GP a useful starting point.
