Vulvodynia: Understanding Chronic Vulval Pain and Treatment in the UK

Vulvodynia is defined as persistent, unexplained pain around the opening of the vagina (the vulva) that lasts for three months or longer. Unlike common infections such as candidiasis (thrush) or bacterial vaginosis, there is no visible sign of infection or skin disease. The pain is genuine and can be distressing, often affecting a woman's ability to sit comfortably, exercise, or enjoy a sexual relationship.

According to NHS clinical guidance, vulvodynia is categorised into two main types: generalised vulvodynia, where the pain occurs in different areas of the vulva at different times, and provoked vulvodynia (vestibulodynia), where the pain is triggered by touch or pressure, such as during sex or when inserting a tampon.

The sensation of vulvodynia varies between individuals, but it is typically described as a burning, stinging, or throbbing feeling. Some women describe it as an 'irritation' or a feeling of rawness. These symptoms may be constant, or they may come and go without an obvious pattern.

• Provoked pain: Sharp pain triggered by contact, such as tight clothing, sitting for long periods, or sexual intercourse.
• Unhinged pain: A background ache or burning that persists even when there is no contact.
• Stinging: A sensation similar to having acid or salt on a small cut.
• Associated symptoms: Many women also experience pelvic floor muscle spasms, which can make any form of penetration very painful.

The exact cause of vulvodynia remains unclear, and it is likely that several factors contribute to the condition. It is not a sexually transmitted infection (STI) and it is not a sign of cancer. Research suggested by NICE (National Institute for Health and Care Excellence) indicates that it may be related to nerve endings in the vulval skin becoming oversensitive.

Potential factors include damage or irritation to the nerves supplying the vulva, past vaginal infections that have sensitised the area, or genetic factors. In some cases, it is linked to other chronic pain conditions like irritable bowel syndrome (IBS) or fibromyalgia. It is important to note that psychological factors are rarely the primary cause, though the stress of chronic pain can certainly worsen the experience.

If you have been suffering from vulval pain for more than a few weeks, you should seek medical advice. Many women feel embarrassed to discuss these symptoms, but GPs are trained to handle these issues with sensitivity. You can speak to a GP online to discuss your history and determine if your symptoms align with vulvodynia.

An online consultation is an excellent starting point to rule out other common issues. A doctor can review your symptoms, check your history of previous treatments (such as repeated thrush treatments that haven't worked), and advise on the next steps. They can also provide a referral to a specialist vulval clinic or a gynaecologist if a physical examination or further tests are required to confirm the diagnosis.

Managing vulvodynia often requires a multi-faceted approach. While there is no 'one-size-fits-all' cure, many women find significant relief through a combination of treatments. NICE guidelines suggest starting with conservative measures before moving to medication.

Self-Care and Lifestyle

• Switch to non-perfumed, emollient soap substitutes for washing.
• Wear loose-fitting cotton underwear and avoid tight jeans or leggings.
• Use a water-based lubricant during intercourse, or avoid activities that trigger pain until the sensitivity settles.
• Try applying cool gel packs to the area to soothe burning sensations.

Medical Interventions

If lifestyle changes aren't enough, your doctor may suggest nerve-modulating medications such as amitriptyline or gabapentin. While these are often used for depression or epilepsy, at lower doses, they are highly effective at 'calming down' oversensitive nerves. Topical anaesthetic creams, like lidocaine, can be applied before sex to temporarily numb the area. Pelvic floor physiotherapy is also highly recommended to help relax the muscles around the vagina.

Because chronic pain can take a toll on mental wellbeing and relationships, holistic support is vital. Cognitive Behavioural Therapy (CBT) can be helpful for managing the emotional burden of chronic pain. If the condition is affecting your relationship, psychosexual counselling may be beneficial. Remember that vulvodynia is a medical condition, and seeking help is the first step toward regaining your quality of life.
