Vaginal irritation and soreness can have many causes, from infections like thrush to everyday sensitivities. The positive news is that most causes are treatable, and there are simple steps you can take to feel comfortable and at ease again.
Here, we’ll explain the most common reasons your vagina might feel sore or irritated, share practical ways to find relief and explain when it’s worth seeking advice from a healthcare professional.
What can cause a sore or irritated vagina?
Several conditions and lifestyle factors can cause vaginal soreness or irritation. These can affect the vulva (the external area around the vaginal opening), the vagina itself or both.
You might also hear the term ‘vaginitis’ – it’s used for several conditions that cause inflammation or irritation in the vagina, which can result in itchiness, pain and swelling.
1. Vaginal yeast infections (thrush)
Thrush – a common yeast infection – can cause vaginal soreness and irritation.
It happens when a yeast called candida, which naturally lives in the vagina, grows too much. Symptoms can include:
- Itching and irritation around the vulva
- Soreness or burning, especially during sex or when you pee
- Thick, white vaginal discharge with a cottage cheese-like texture
Thrush can disrupt your day-to-day comfort, but it’s not a sexually transmitted infection (STI), and the good news is, it can be easily treated. Antifungal medicines, such as tablets, pessaries (a tablet you insert into your vagina) or creams, can help relieve the irritation and treat the infection.
If thrush keeps coming back – more than four times in a year – it’s worth speaking to your doctor. They can help figure out why and suggest ways to prevent it from returning, so you can get longer-term relief.
2. Bacterial vaginosis (BV)
BV is another common vaginal condition caused by an imbalance in the bacteria naturally found in the vagina. It may lead to:
- A change to your vaginal discharge, such as it becoming thin and watery and greyish-white
- Vaginal discharge with a strong fishy smell, especially after sex
BV doesn’t usually cause soreness or itching – in fact, about half of women with BV don’t have any symptoms at all! If itching or soreness is your main concern, another cause might be more likely.
BV is usually treated with antibiotics prescribed by a doctor. Some people also use pH-balancing gels to help restore the vagina’s natural environment. If your symptoms keep returning, your GP or sexual health clinic can help you find a more tailored approach.
3. Irritation from products or clothing
Sometimes vaginal irritation has nothing to do with infection – it can simply be a reaction to seemingly harmless everyday products or fabrics. Triggers can include:
- Harsh soaps
- Scented hygiene products
- Vaginal sprays or douches (washing or cleaning out the vagina with water or other fluids)
- Fabric conditioners or strong detergents
- Tight-fitting clothing
If you’re sensitive or allergic to certain products, you might notice burning or itching when you use them.
If this sounds familiar, the kindest thing you can do for your intimate skin is to give it a break from potential irritants. Switch to gentle, fragrance-free products and loose-fitting cotton underwear – these simple changes can help ease symptoms and reduce your chances of irritation returning.
4. Sexually transmitted infections (STIs)
Some STIs can cause vaginal soreness or irritation. Conditions like genital herpes and trichomoniasis are fairly common, but with the right treatment, symptoms can usually be managed effectively.
If you think you might have an STI, visiting a sexual health clinic or GP is the best step. They’re there to support you, not judge, and getting tested means you can access the right treatment and protect both your health and your sexual partner’s.
5. Hormonal changes
When oestrogen levels drop – for example, after menopause, during breastfeeding or when using certain hormonal contraceptives – it can impact your vaginal health.
These hormonal changes can make the walls of your vagina drier and affect how much vaginal discharge or fluid you have.
This may lead to vaginal dryness, which can cause soreness, irritation, and sometimes itching. Sex might feel uncomfortable or even painful, and you may notice more frequent urinary tract infections.
If hormonal changes are affecting you, there are ways to feel more comfortable. Vaginal moisturisers and lubricants can help with day-to-day dryness or during sex, and in some cases, your doctor may recommend hormone-based treatments to restore balance.

- BV: A doctor can prescribe antibiotics to treat the condition. Sometimes a vaginal gel, like Canesbalance®, can also be used to help restore your vagina’s natural balance
- Irritation from products or clothing: Identifying and avoiding the trigger is key. Pair this with breathable cotton underwear and, if needed, a gentle soothing product like Canescool® Soothing Cream Gel to help calm your intimate area
- Hormonal dryness: Vaginal moisturisers or lubricants can help restore comfort day-to-day or during sex. In some cases, your doctor may also suggest hormone replacement therapy (HRT)
When you’re experiencing vaginal irritation, the right treatment can make a real difference – and in many cases, relief comes quickly once the cause is addressed. A pharmacist or doctor can guide you towards the option that works best for you.
Self-care tips for comfort and prevention
No matter the cause, these simple habits may help reduce the risk of irritation and keep your intimate area healthy:
- Wash around your vagina gently with warm water, and use an unperfumed soap only if needed,
- Avoid douching or scented products in or around your vagina
- Wear loose, breathable cotton underwear
- Avoid clothes that trap heat and moisture
- Consider using pads instead of tampons during your period
- Use condoms and lubrication during sex
Keeping these simple habits in mind can make a real difference to your comfort and vaginal health. Everyday care goes a long way, and if irritation sticks around, a pharmacist or doctor can help.
When to see a doctor
If you’re unsure what’s causing vaginal irritation and soreness, or your symptoms worsen or don’t improve, it’s a good idea to check in with your doctor or visit a sexual health clinic.
You should also seek medical advice if:
- You have vaginal discharge that’s unusual for you
- You notice unusual bleeding (for example, between periods, after sex or post-menopause)
- You’re pregnant or breastfeeding
- You have symptoms of thrush for the first time or thrush that keeps coming back (more than 4 times in 12 months)
- You think you may have BV
- You think you could have an STI
Getting checked can give you peace of mind and help you find the right treatment quickly.
Vaginal irritation and soreness are common, usually treatable, and nothing to be embarrassed about. Whether it’s caused by thrush, BV, STIs, product-related irritation or hormonal changes, feeling confident and comfortable again is important. Trust your instincts and reach out to a healthcare professional if needed.
