Swollen Labia Minora and Majora: Causes (One Side) Pain, Treatment

Vaginal swelling does not only cause discomfort but also stress of what could have gone wrong down there.

Several factors could be causing your vaginal lips to swell up. While most of these factors are nothing to worry about, others will need you to visit your doctor immediately.

Less severe cases of swollen labia can be simply gotten rid of at home using natural treatments which are quite effective.

What does labia edema mean?

Also known as labia edema, labia swelling occurs when the tiny blood vessels are injured leading to fluid leaking into the surrounding tissues. When the fluid builds up, it makes the tissues edematous or inflamed.

Causes of swollen labia

There are several causes of labia edema. Here are the most common reasons:

1. Pregnancy

During the growth of the baby, the uterus exerts pressure on the pelvic organs causing the blood vessels to dilate and enlarge.

Blood circulation is highly affected, there is poor venous drainage, and the blood seems to pool along the pelvic organs and the lower limbs. For this reason, the labia appear swollen.

2. Yeast infection

The common cause of vulvovaginitis (Swelling of the vulva, labia and vagina) in most women is yeast infection. Candida albicans is the fungi causative organism of such infections. A yeast infection can lead to infertility if not treated early enough. It spreads very fast to the cervix causing inflammation and even bleeding.

  • It is important to visit your doctor early enough, to help diagnose and prescribe treatment accordingly.

3. Trauma

Some women could be allergic to latex (condom) without their knowledge. Swelling on either the labia minora or majora, especially after sex could be a sign of either lubricant use or latex allergy.

For this reason, it is always advisable to go for latex-free condoms and water-based lubricants. Any trauma or bruises during vacuum childbirth might also lead to labia edema.

4. Allergy

Semen allergy, also known as human seminal plasma hypersensitivity is another factor that leads to labia edema after sex.

The symptoms associated with this condition include intense burning sensation during sex, pain and vaginal swelling, this usually occurs about an hour from the last ejaculation.

  • The only way to know whether you are sensitive to your partner semen is to go for the hypersensitivity tests.

Another sure way to determine the existence of hypersensitivity is to use a condom for a short while, to note the difference. If no allergy or symptoms occur after the condom use, then you can conclude that you have a semen allergy, and look forward to visiting your doctor for advice and further tests.

5. Cysts

The vulva has numerous glands that secrete lubrication. If the duct of the gland blocks, a swelling will occur. At the start, the swelling might be painless, but in case infections occur, you might experience severe pain.

6. Abscess

An abscess occurs when there is localized pus as a result of an infection. The causes may include blocked ducts, infected hair follicles or pulled hair. In such instances, you need to visit your doctor, to help drain the abscess using standard medical procedures.

7. Hypoalbuminemia

Low albumin can certainly lead to fluid leakage into the nearby tissues. Albumin is protein in nature. The main function of proteins in the human body is to act as a sponge, holding fluids back from getting into the blood vessels. Low quantities of this type of protein lead to edema not only in the genitalia but also the entire body.


Swollen labia can be a major source of discomfort. Here are the common labia inflammation symptoms that you might notice:

  • Sore vagina and blistering
  • Discomfort during urination
  • Itchiness and irritation in the genital area

Why is my labia majora swollen on one side?

In some cases, you may have one swollen vaginal lip. This is common with the outer lips although you may experience it with the smaller, less visible lips.

Swollen labia majora on either side is often a sign of cysts or abscesses. Other factors that could be contributing to this include trauma, allergy, and infection. It is recommended that you visit your gynecologist to help you figure out the cause of the swelling.

3. Therapies

In most of the time, swollen labia is as a result of vaginal infections. Below are tips to help you prevent yeast infection that could result to swollen labia:

  • Avoid using soap during your bath. Majority of the soaps available in the market today are full of chemicals and perfumes that are likely to cause allergies
  • Avoid douching. Douching may make you feel cleaner, but the truth of the matter is it worsens your symptoms because it removes healthy bacteria lining the vagina. An infection is bound to occur due to depletion of good bacteria.
  • Avoid using tampons during an infection, pads are recommended instead. Tampons ‘push’ or helps in ascending the infection to the cervix.
  • Do not wear tight underwear. Wear cotton underwear instead of the synthetic ones. Cotton allows free movement of air in and out of the vagina, hence gives no room for growth of micro-organisms.
  • Wipe your genitalia properly. The correct way is from front to back. This is to avoid the spread of bacteria to the genitalia.
  • Do not share washing tubs. Make sure you thoroughly clean the bathroom before using.
  • Always practice safe sex, use of condoms is highly recommended.
