Key Takeaways

  • The most common symptoms of a yeast infection include cottage cheese-like vaginal discharge and itchiness. They can sometimes cause sores. These sores often look like red, raw patches of skin that can resemble paper cuts.
  • The sores associated with yeast infections are not solid bumps or blisters. These kinds of sores may be a sign of an STD like genital herpes and should be investigated by a doctor.
  • If you have yeast infection sores, focus on keeping your genital area clean and dry and taking your antifungals exactly as your doctor has prescribed. You can also supplement your treatment by taking a daily vaginal probiotic.

Introduction

Yeast infections often come with a few tell-tale symptoms, most of which are pretty uncomfortable. These include thick, cottage cheese-like discharge, vaginal itching, and stinging or burning during urination. But what about sores? Do yeast infections ever involve painful, red, almost blister-like sores in the genital area? Or are they a sign of something else?

If you are experiencing unexplained sores, you probably feel a little freaked out. Hopefully, after reading this today, you’ll have the answers to stop worrying and start taking action.

Understanding Yeast Infections

Before we can understand how yeast infections might cause sores, we have to understand what a yeast infection is and how it behaves in the body. Essentially, yeast infections are caused by an overgrowth of the fungus Candida1. While we will be talking about vaginal yeast infections, yeast infections can also occur in the mouth, throat, and folds of the skin.

Symptoms of a vaginal yeast infection include: 

  • Vaginal discharge that is thick, white, and odorless2
  • Itchiness
  • Redness
  • Pain when urinating

But self-diagnosing a yeast infection can be difficult, as symptoms can often overlap with other common infections like BV or UTIs, though in the case of BV, the discharge is often thin, gray-ish, and accompanied by a strong or fishy odor3.

Because there is so much overlap in symptoms, if you ever suspect a vaginal infection, you should always see your doctor to confirm a diagnosis.

An In-Depth Look at Yeast Infection Sores

 

Text explaining that yeast infection sores are raw or cracked patches of skin around the groin caused by extreme inflammation from Candida overgrowth, and are flat to the touch, not a bump or blister. Illustrations include microscopic views of Candida fungi.

 

Along with unusual vaginal discharge and itching, yeast infections can also cause sores to the vulva, anus, and skin folds of the genital area. But it’s important to know what these look like (and don’t look like) so you don’t confuse them for the sores associated with genital herpes.

Yeast infection sores are often described as raw or cracked patches of skin around the groin area. Some people describe them as looking and feeling almost like paper cuts. Generally, these sores are caused by extreme inflammation brought on by Candida overgrowth and are flat to the touch and not a bump or blister. Generally, bumps and blisters are a sign of something else. As for what that “something else” could be, we will dive into that in just a bit!

Yeast Infection Sores vs Bumps

 

Text comparing yeast infection sores and vaginal bumps: yeast infection sores are open, red, raw areas of skin that are typically painful, while vaginal bumps are raised, firm areas of skin that are less painful. Illustrations include a microscopic view of Candida fungi and a diagram of the vaginal area.

 

It’s important to understand that when we are talking about yeast infection sores, we are not talking about bumps. Though people think the words “sores” and “bumps” are interchangeable, they refer to different things. Sores are open, red, raw areas of skin. This is different from bumps, which are raised areas of the skin that often feel firm or solid to the touch. And while sores are typically quite painful, bumps are less painful or not painful at all.

What bumps and sores have in common, though, is that they should never be ignored. While sores are often associated with severe yeast infections, there could be other reasons, too, that only a doctor can identify for sure.

Symptoms of Severe Yeast Infections

While sores can be a symptom of a yeast infection, they are not an overly common symptom, and if they are widespread, they are generally a sign of a severe yeast infection.

Other signs of severe infection include:

  • Extensive redness
  • Extreme swelling
  • Fever

While any sign of a yeast infection should warrant a call to your doctor, signs of severe infection require immediate attention. While mild yeast infections can often be treated using over-the-counter antifungals, severe outbreaks may require more aggressive, prescription treatment4.

Yeast Infection Sores vs Herpes

While symptoms of a mild yeast infection may be confused with symptoms of another infection like a UTI, the symptoms of a severe yeast infection (and yeast infection sores in particular) can be confused with the sores associated with genital herpes, though there are some key differences in appearance and other associated symptoms.

Though we will get into these differences next, it’s important to know that you should never attempt to diagnose yourself. You should always seek a doctor’s opinion. Genital herpes is an STD, which means that misdiagnosis can have serious health consequences for you or a sexual partner.

Herpes: An Overview and Its Symptoms

Like we said, genital herpes is an STD or sexually transmitted disease. This means that it is a disease that is passed from person to person exclusively through sexual contact, which can include vaginal sex, oral sex, or anal sex.

When we talk about contracting herpes, we are talking about the transmission of one of two viruses:

Herpes simplex virus type 1 (HSV-1) or herpes simplex virus type 2 (HSV-2)5.

Genital sores are the tell-tale sign of genital herpes, and these sores differ from yeast infection sores. The sores associated with yeast infections can vary in size, while the sores associated with genital herpes tend to appear more uniform and resemble blisters. When these blisters pop, they can expose raw, red skin underneath, which can sometimes be confused for yeast infection sores. Again, this is why a doctor’s evaluation is so important.

While yeast infection sores are often accompanied by odorless, cottage cheese-like discharge, genital herpes sores are associated with symptoms like:

  • Smelly genital discharge
  • Bleeding between periods (if you have a menstrual cycle)
  • Swelling of the lymph nodes
  • Flu-like symptoms

While genital herpes, like all STDs, cannot be cured, these painful outbreaks can be managed with the help of your doctor. 

When to Consult a Medical Professional

No matter if it’s mild or severe, If you ever suspect you have a vaginal infection, STI, or STD,  you should make an appointment with your doctor.

If your doctor diagnoses you with a yeast infection, you must continue to monitor your symptoms and make a follow-up visit if you feel like symptoms are persistent, despite treatment, or causing you severe discomfort.

Managing Yeast Infections Sores

The best way to manage yeast infection sores is to treat the fungus causing the infection, which is generally done through over-the-counter or prescription antifungal medication. Your doctor will advise you which option is best for you during your appointment.

Other than that, make it a point to keep the genital area clean and dry while your sores are healing. You can do this by wearing breathable cotton underwear and loose bottoms. 

Prevention and Long-Term Health Maintenance

Wearing cotton underwear isn’t just a good idea when you have yeast infection sores. It is a good idea in general since it allows the area to breathe, preventing moisture build-up that enables yeast growth.

Other good hygiene measures for preventing yeast infections include reducing sugar intake since sugar also fuels yeast growth, and changing your underwear and pants promptly after working out6.

If you have recently had a severe yeast infection or have had multiple infections, also consider taking a daily probiotic to help restore your vaginal microbiome and give it the good bacteria it needs to fight off the bad. Just look for one like Happy V’s Prebiotic + Probiotic that is doctor-formulated for vaginal health and contains clinically proven strains of Lactobacillus.

FAQ

Can a yeast infection actually cause “sores”?

Yes, it can. In this context, “sores” usually means raw, cracked, irritated patches on the vulva/groin skin caused by intense inflammation from Candida overgrowth. People often describe them as feeling like tiny paper cuts, and they’re typically flat, not raised.

What do yeast infection sores usually look and feel like?

Think red, raw, open-looking areas that sting or burn, especially if urine touches them. They can show up on the vulva, around skin folds, and sometimes around the anus. They’re often paired with classic yeast symptoms like itching and thick, white discharge.

How do I know if my yeast infection sores are mild or severe?

Generally, any kind of sore is considered a sign of a more severe yeast infection and should be seen by a healthcare provider ASAP.

Do yeast infection sores look like blisters?

Usually no. Yeast “sores” tend to be raw patches or fissures (cracks), not fluid-filled blisters. Blisters are a bigger red flag for something else, especially herpes, and are worth getting checked instead of guessing.

What’s the difference between yeast infection sores and vaginal bumps?

Sores are typically open/raw and painful. Bumps are raised areas that feel more solid and are often less painful (or not painful). The article is pretty blunt about this: bumps and blisters usually point away from “simple yeast.”

How do I tell yeast sores apart from genital herpes?

Herpes usually shows up as clusters of blisters that break and become painful sores, and the blisters tend to look more uniform than yeast-related raw patches. A first herpes outbreak can also come with flu-like symptoms and swollen glands. If you’re seeing blisters or you’re unsure, get evaluated.

Can I have a yeast infection and herpes (or another STI) at the same time?

It’s possible to have overlapping issues, which is why self-diagnosis gets messy fast. If symptoms don’t match your usual yeast pattern, or you have new sores after sexual contact, testing is the smartest move.

What are the “classic” yeast infection symptoms that often come with sores?

The common combo is itching, vulvar redness/swelling, burning (especially with urination or sex), and thick, white, curdy discharge. Not everyone gets every symptom, but that pattern is the usual yeast story.

Why is it so easy to confuse yeast with BV or a UTI?

Because symptoms overlap. You can get burning, irritation, and discharge changes with multiple infections. BV often leans toward thin, gray-ish discharge with a fishy smell, while yeast is more likely thick/white/odorless. If you’re not sure, it’s worth confirming with a clinician.

When should I see a doctor instead of treating at home?

If you suspect any infection or STI, make an appointment, especially if symptoms are severe, keep coming back, or don’t improve with treatment. Also go in if you have blisters, unusual bleeding, fever, swollen glands, or pain that feels intense or “not normal for you.”

What’s the best way to treat yeast infection sores?

Treat the yeast infection itself with the antifungal plan you and your provider choose (over-the-counter or prescription). The sores usually improve as the inflammation calms down. Skipping doses or stopping early can drag things out.

What can I do while the sores are healing (so it hurts less)?

Keep the area clean and dry, wear breathable cotton underwear, and choose loose bottoms so you’re not trapping moisture or adding friction. Basically: reduce rubbing, reduce dampness, and let irritated skin calm down.

Should I have sex if I have yeast sores?

It’s usually a bad idea. Sex can worsen irritation, slow healing, and increase discomfort. If there’s any chance the sores are from herpes or another STI, sex also risks transmission. Waiting until symptoms fully resolve is the safer move.

How long do yeast infection sores take to heal?

There’s no perfect timeline, but you should notice improvement as the antifungal treatment works and the skin gets a break from moisture and friction. If things aren’t improving or keep coming back, that’s a sign to re-check the diagnosis (because not every “yeast-like” problem is yeast).

How can I lower my chances of getting yeast infections (and irritation) again?

Prevention is mostly about not creating a yeast-friendly environment: avoid staying in damp clothes, keep things breathable (cotton underwear helps), and take antibiotics only as prescribed. If you’re prone to recurrences, it’s worth talking to your clinician about a longer-term prevention plan."

How long do yeast infections last?

Once you begin treatment, mild infections often resolve within a few days, though more severe or complicated infections can take longer.
