What is herpes?

Herpes is almost always the most common cause of blisters and sores on the genital area. This disease is caused by an infection with a virus from the herpes simplex virus family. Types of two herpes simplex viruses or HSV type2 cause most vesicles, blisters, and genital sores.

Remember that blisters and sores on the genital area are not necessarily a sign of an infection or sexually transmitted disease, such as genital herpes. Sometimes lesions develop that resolve on their own.

In the following, you will become more familiar with the important causes of genital blisters


Symptoms of genital herpes

Features and some symptoms associated with these lesions may include the following:

  • The lesions are round and slightly prominent that form in and around the vagina
  • Waste can be prickly
  • Lesions are sometimes painful
  • They are sensitive to touch and can be associated with abnormal vaginal discharge
  • Occasionally, blisters and lesions in the genital area can be asymptomatic.


Symptoms associated with these sores and blisters may also include one or more of the following:

  • It can be itchy
  • It can be painful
  • It can be accompanied by burning
  • It can be accompanied by bleeding
  • It can cause pain during intercourse
  • It can cause painful urination
  • It can be accompanied by foul-smelling vaginal discharge
  • It can increase soft and odorless discharge

We emphasize that sometimes sexually transmitted infections such as genital herpes or genital warts can be asymptomatic, this asymptomatic sexual partner puts a person at high risk of infection.


What are the causes of blisters in the genital area?

There are a number of skin problems that can be associated with blisters, sores, itching, pain, burning and irritation of the genital skin.

These factors include:


  • Eczema or dermatitis:

They are skin inflammations that usually follow allergic or allergic reactions. Eczema occurs as watery blisters on inflamed and itchy skin.


  • Contact dermatitis:

Inflammation and blistering can occur following irritation of the site with detergents, perfumes, chemicals and synthetic fibers of underwear.


  • Vulvovaginitis:

The vulva is the area of ​​the female external genitalia that includes the minor labia and the entrance to the vagina and clitoris. Inflammation and infection of these components are called vulvovaginitis

Inflammation and infections of the vulva and vagina can be associated with sores and sometimes blister-like rashes.


  • Bartollen cyst in women:

On either side of the vagina are two pea-sized glands called Bartholomew's. These glands secrete fluid that keeps the vagina moist.

Obstruction of the tubes that carry the fluid produced by these glands into the vagina causes fluid to accumulate inside the gland and increase the size of the gland to form Bartholomew's cyst. Bartholomew's cysts are benign and do not become cancerous.

  • ingrown hair
  • Infection and inflammation of the itchy area
  • Folliculitis (inflammation of the hair follicles)




Aside from these non-serious factors, STIs are the most common cause of genital sores and blisters. Inflammation and sexually transmitted infections are called STIs as an abbreviation.

STIs are transmitted to a healthy partner if they have vaginal, anal and sometimes oral sex with an infected person.

Remember that infected sex toys can also transmit these infections.

The major STIs associated with genital ulcers are:

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


  • Genital herpes:

We said that one of the most common causes of genital blister is genital herpes, which is caused by infection with the herpes simplex virus.

Genital herpes lesions vary greatly in shape and size, the lesions can be in the form of pimples or slightly blistered and full of fluid.

Rupture of these blisters can lead to the formation of yellowish crusts that can be accompanied by pain and increased vaginal discharge.

Pain when urinating is more common in women than men


  • Genital warts:

Genital warts are usually pink or skin-colored bumps that can be asymptomatic. These lesions appear one to eight months after sexual contact with the carrier. Sometimes they bleed and become painful after the injury, but are usually painless.


  • Chancroid:

Chancroid is a type of STI caused by a type of bacterium called Hemophilus biceps

Chancroids are very similar in shape to herpes blisters

These lesions have the following characteristics:

  • It apppears on the penis or around the entrance to a woman's vagina
  • Wounds can become purulent
  • They are painful
  • They are separate and distinct from the surrounding tissue
  • The base of the blisters and wounds is covered with a yellow-gray substance
  • Bleeding occurs rapidly as the blisters are scratched

Along with blisters and painful sores, swollen lymph nodes in the area may also be present. Chancroid blisters may be associated with abscesses.


  • Syphilis:

It is a type of STI caused by a bacterium called Treponema pallidum

Ten to ninety days after infection, the primary syphilis phase begins, in which small, painless red granules that look like small blisters form in the genital area. These pimples quickly turn into sores. These sores heal within one to two months without treatment. Genital sores and blisters occur in the early stage of syphilis


  • Treatment of syphilis:

With proper treatment, these lesions will disappear in one to two weeks. Sometimes the sores are inside the vagina or anus. Groin lymph nodes enlarge in affected men.

We have another term called Friction blister

These blisters can be caused by wear and friction

These blisters are prominent and contain clear fluids and usually cause pain and itching when touched.


The final words

If you have had high-risk sex and have blisters or a genital rash, it is important to be examined by a doctor as soon as possible.
