a Bump on the Vulva: Causes and When to Seek Help

There is a bump on the outer labia that resembles a pimple?

Doctor, I would like to ask about something I discovered today, the 26th.
While showering, I noticed a bump on my labia that looks like a pimple (slightly swollen).
I had sexual intercourse about a week after my menstrual period with my regular partner.
The bump is approximately less than 1 centimeter in diameter, does not itch, and is slightly painful when pressed.

1.
What kind of infection could this be? What possible conditions could it indicate?
2.
Will it resolve on its own? (Will it improve in a few days?) Or should I see a doctor?
I appreciate your help in clarifying these concerns, and if medical attention is necessary, I would like to seek it as soon as possible to prevent it from worsening.
Thank you, doctor.

1.
It is a bacterial infection (most commonly caused by Staphylococcus aureus), frequently encountered in outpatient settings, medically referred to as furuncle or abscess, and sometimes called cellulitis.
It is not a sexually transmitted infection, as there are opportunities for infection through regular activities such as bathing, dressing, and eating.
2.
Individuals with strong immune systems may recover naturally, but it is best to see a doctor immediately to prevent the condition from worsening.

More Info

When it comes to a bump on the vulva, there are several potential causes, and understanding these can help you determine the best course of action. Given your description of the bump resembling a pimple, measuring less than 1 cm, and being slightly painful when pressed, it could be a number of things, including:
1. Folliculitis: This is an inflammation of the hair follicles, often caused by bacteria or irritation. It can appear as small, red bumps that may be tender to the touch.

2. Cysts: Sebaceous cysts can form when the sebaceous glands become blocked. These are usually painless but can become inflamed or infected, leading to discomfort.

3. Genital Warts: Caused by the human papillomavirus (HPV), these can appear as small bumps or growths in the genital area. They may not always be itchy or painful.

4. Herpes Simplex Virus (HSV): If you have a history of genital herpes, a bump could indicate an outbreak. This would typically be accompanied by other symptoms such as itching, burning, or flu-like symptoms.

5. Bartholin's Gland Cyst: If the Bartholin's glands become blocked, a cyst can form, which may cause discomfort and swelling.

6. Other Infections: Various infections, including sexually transmitted infections (STIs), can present with bumps or lesions in the genital area.

When to Seek Help
Given that you have recently engaged in sexual activity, it is prudent to consider the possibility of an STI, especially if the bump does not improve or worsens over the next few days. Here are some guidelines on when to seek medical attention:
- Persistent Symptoms: If the bump does not resolve within a week or worsens, it is advisable to see a healthcare provider.

- Accompanying Symptoms: If you experience additional symptoms such as fever, increased pain, discharge, or any systemic symptoms, seek medical attention promptly.

- Changes in Appearance: If the bump changes in size, color, or begins to ulcerate, it is important to get it evaluated.

Self-Care and Monitoring
While some bumps may resolve on their own, it is essential to monitor the situation closely. Here are some self-care tips:
- Avoid Irritation: Wear loose-fitting clothing and avoid tight underwear to reduce irritation.

- Good Hygiene: Maintain good genital hygiene, but avoid harsh soaps or douches that can disrupt the natural flora.

- Do Not Squeeze: Avoid squeezing or picking at the bump, as this can lead to infection.

Conclusion
In summary, while the bump you described could be benign, it is essential to monitor it closely and consider seeking medical advice, especially given your recent sexual activity. A healthcare provider can perform a thorough examination, possibly conduct tests, and provide a definitive diagnosis and appropriate treatment if necessary. Early intervention can prevent complications and ensure better health outcomes. If you have any concerns about STIs or other infections, do not hesitate to reach out to a healthcare professional for guidance.
