Painful Swelling on the Labia: Possible Causes and Concerns

There is a foreign body in the labia?

Four days ago, during the third or fourth day of my menstrual period, I felt an unusual pain in the left labia majora.
Two days later, after my period ended, I self-examined and found a red, swollen lesion about 0.5-0.7 cm in size on the left labia majora, with a white, pus-like tip, resembling an acne lesion.
There are no abnormal vaginal discharge or odor, and I have no other discomfort.
I am unsure what condition this symptom may indicate.
I am currently studying in the UK and would like to understand the possible situations before seeking medical attention.
Thank you.

More Info

When experiencing painful swelling on the labia, particularly with the symptoms you've described, there are several potential causes to consider. Given that you noticed this swelling during your menstrual period, it is important to keep in mind that hormonal fluctuations can lead to various changes in the body, including the genital area.

One possible cause of the painful swelling you are experiencing could be a bartholinitis. This condition occurs when the Bartholin glands, located on either side of the vaginal opening, become blocked or infected. The blockage can lead to the formation of a cyst, which may become inflamed and painful. The presence of a white head, similar to a pimple, suggests that there may be pus involved, indicating an infection.

Another possibility is a folliculitis, which is the inflammation of hair follicles. This can occur in the genital area and may present as red, swollen bumps that can be painful. If there is a white head, it may indicate that the follicle is infected.

Additionally, herpes simplex virus (HSV) could be a consideration, especially if you have a history of genital herpes. This viral infection can cause painful blisters or sores in the genital area. However, you mentioned that there are no unusual discharges or odors, which makes this less likely, but it is still a possibility to keep in mind.

Contact dermatitis is another potential cause, which can occur due to irritation from soaps, detergents, or other products that come into contact with the genital area. This would typically present as redness and swelling but may not necessarily have a white head.

Lastly, vulvar vestibulitis or vulvodynia could be considered, which are conditions characterized by chronic pain in the vulvar area without an identifiable cause. However, these conditions usually do not present with a localized swelling or a white head.

Given that you are currently studying in the UK, it is advisable to seek medical attention from a healthcare provider for a proper diagnosis and treatment. They may perform a physical examination and possibly take a sample if there is any discharge or fluid present to determine the exact cause of the swelling.

In the meantime, it is important to avoid any irritants, maintain good hygiene, and refrain from any activities that may exacerbate the condition, such as tight clothing or sexual intercourse until you have been evaluated by a healthcare professional.

In summary, the symptoms you are experiencing could be due to a variety of conditions, including bartholinitis, folliculitis, herpes simplex, contact dermatitis, or vulvar vestibulitis. It is crucial to consult with a healthcare provider to obtain an accurate diagnosis and appropriate treatment.
