Vulvar anatomy

The vulva is the external part of the female genitalia. “It protects a woman’s sexual organs, urinary opening, vestibule, and vagina and is the center of much of a woman’s sexual response.”[] the external female genitalia comprise of:

  • Labia majora and labia minora, these are the fleshy lips around the vagina
  • The opening of the birth canal
  • Clitoris, a small group of tissues covered with a thin flap of tissue. It is the main source of sensation during a sexual act
  • Other parts include the mons pubis, a bulb of a vestibule, urinary meatus, minor and major vestibular glands. Pudendal cleft, sebaceous glands, and pubic hair are also included.

This area is prone to many disorders that can lead to itching or inflammation and thus the development of sores on vag lip among other vulva disorders.

Causes of sores

As we had highlighted before, vulva sores have got a number of causes. They involve things to do with Sexual Transmitted diseases, skin disorders, cancers and more conditions. Let`s look into the details of the causes.

1. Sexual Transmitted Diseases (STIs)

STIs are the most common causes of sores on the vulva. Many of them are usually contagious and can be spread through vaginal, oral or anal sex. Sharing sex toys can also spread the same. Examples of STIs that are can cause them include:

  • Genital herpes
  • Chancroid
  • Syphilis
  • Genital warts
  • Granuloma inguinale
  • Molluscum contagiosum

In many cases, it is a challenge to tell whether the vulva sores are due to STIs or due to some other causes, therefore, you should get tested for STIs especially if you are sexually active or you just hooked a new sex partner. This is the only way to know whether you sores on vulvar is due to STIs or other conditions.

2. Skin Conditions

Besides STIs, chronic skin conditions are another major cause of vulva sores. Such skin conditions are usually accompanied by other symptoms such as itching, inflammation or painful blisters. Here is the detailed information about skin conditions that can cause them:


This is an inflammation or infection of the vulva and vagina that can cause vulvar irritation and redness. This condition is prevalent in both girls and women of all ages and has variant causes. The major cause of this condition is bacteria. Other causes may also include allergic reactions, STIs, viruses, Yeast, chemical irritants as well as environmental factors. The symptoms include irritation, itching, inflammations, smelly virginal discharge and discomfort during urinating. Treatment for this infection will depend on the underlying causes.

Atopic Dermatitis

This is a chronic skin condition that is characterized by dry, itchy skin. It is skin inflammation due to allergies. There are several types of atopic dermatitis. The major symptom is a dry, itchy skin that may turn into a red sore.

Contact Dermatitis

This is a common cause of rash or sore when the skin comes into contact with a substance that triggers allergic or irritation. These include harsh soaps, detergents, shampoos, perfumes, lotions and even condoms and sex toys for our case. Sore from this root may be very itchy. Replacing our soap or these allergens and irritants may be crucial to relieving this worrisome condition.


This is an inflammation or infection of hair follicles. This skin condition initiates as a red, tender area near the base of one or more hair strands. It can be caused by bacteria, yeast or fungus. This condition can also cause them.

3. Ingrown hair

Vulva itching and burning which can result in sore can also be due to ingrown hair. The major cause of ingrown hair in the vulva is hair removal methods but this condition also tends to be common in women during pregnancy and periods. Having too short and sharp hair, shaving using a blunt razor, waxing after shaving all are enough to cause ingrown hair. If you put on tight undergarments or if you have naturally curly hair, then you are also prone to ingrown vulva hair.

Why do I suffer ingrown hair on my pubis during periods and pregnancy? Well, during the mentioned stages, there is a hormonal imbalance that may influence the sebaceous glands to produce more sebum (we`ll discuss this in detail later in this article). This excessive sebum may clog the pores and hence lead to ingrown hair. Symptoms of ingrown hair include pus-filled boils, itchy bumps and painful sores among other symptoms.

Remember shaving with a razor is enough to irritate this area and hence leading to the formation of the sores.

4. Clogged pores

Pimples on the vulva area of females may be as a result of clogged pores. This results from excessive production of sebum that will sum up with dead skin cells to block the pores. This will thereafter attract bacterial infection resulting in the formation of other kinds of acne on the vulva leading to sores or painful bumps on the vulva area. This could be due changes in some levels of hormones that influence the sebaceous gland to be overactive

5. Pubic Lice or Crabs

“Pubic lice are also known as pubic crabs cause sores that are itchy and may be identified by dandruff at the base of the pubic hair.” []. Depending on the intensity of the infection, resultant dandruff may be grayish or whitish. Here is how one may contact pubic lice:

  • Sharing clothes and undergarment
  • Sleeping in beds that have lice on the beddings
  • Having sex with a partner already having the lice on their pubis
  • Poor hygiene

6. Sore on vulva from Cancer

Cancer on vulva or skin usually may begin as small bumps that won’t go away or become chronic. Many of such bumps become itchy and keep on growing bigger. When you scratch the itchy bumps, new revolting sores may spring. Other symptoms of this cancer include the following:

  • Bleeding pimples and bumps
  • Pelvic pain
  • Sores or painful, itchy bumps
  • Blood in urine
  • Smelly vaginal discharge
  • Bloody vaginal discharge
  • Pain while urinating

All the symptoms mentioned above does not necessarily mean you have a vulva cancer, they may originate from other sources, and therefore you should visit your doctor for proper diagnosis.

7. Having a dry vulva

If your vulva becomes dry maybe because you don’t often moisturize it, then you may also be a victim of sores but how? Well, when the vulva gets dry, itching and irritation may pop up. Scratching the itchy or inflamed areas may lead to the development of sores. One trick is to keep your vulva moisturized and well hydrated.

8. Other causes

Apart from the cause explained above, more causes may include irritation from unprotected sex, sweating and vaginal secretions, sexual trauma or scratches, tight-undergarments, condom allergies, flu-types viruses that can cause vulva ulcers, lymphogranuloma venereum, and psoriasis among other causes


Symptoms are basically determined to be the underlying causes of the sores. For instance, symptoms of sores from STIs may vary from symptoms of a sore allergies reaction, though some causes may also have similar symptoms. The causes will also determine the severity and the treatment of the vulva sores. Here we`ll explore some general symptoms that may directly point out vulva sores.

  • A pimple and rash of vulva area that may be itchy
  • Small bumps on the vulva that may be reddish
  • Bleeding on the vulva
  • Pain or burning feeling while urinating
  • Fluid-filled rashes that may open up to create crusty layers on it

Whether mild or severe, any symptom must be examined by a doctor. You never know, it may be due to STIs or serious health condition that if not treated in time, may result in life-threatening symptoms.

Sores on vulva after periods

A good number of our customers have raised a complaint about vulva sores after periods. First, I want to put it clear that, there are many changes that occur in the levels of hormonal during this period. When the estrogen level declines, the vulva will get drier and then the development of sores.

Again, a sanitary towel used during menstruation may be to blame. Some of them may irritate your vulva based on the material they are made of. Another point is based on vaginal discharges. The sanitary towels will absorb vaginal secretions and even the sweat and all may irritate the vulva leading to the development of the revolting sores. The common symptoms are sores on the vagina, burning and itching vag or blisters on vags lip among other symptoms.

“During monthly periods, sanitary towels may cause serious sores due to the damp and hot environment. The menstrual flaws irritate the skin on the vagina and the genital areas,” confirms

Sores during Pregnancy

Are you pregnant and just discovered itchy tiny bumps on your vulva? Well, don’t panic. Many pregnant women are also struggling with the same problem. So how is this possible? First, you may have contracted a sexually transmitted infection from the sex partner who impregnated you. It may be also due to the excessive production of sebum resulting from hormonal disorders in this stage. These may lead to pimples sores or sores from other forms of acne. Symptoms may be vaginal itching, blisters on vagina or rash on vagina lips.
