Could it be folliculitis?


A few days ago, after swimming, I noticed a small red bump on my labia that has been itchy and somewhat painful to the touch.
Since my menstrual period had not completely ended on the day I went swimming, I'm unsure if this is an infection or something else.
Doctor, is this serious? What should I do? Thank you!

I'm sorry, but an online diagnosis cannot be made.
You can choose to ignore it for a few days and see if it improves.
If it continues to be a concern, please visit a dermatologist in person.

More Info


It sounds like you are experiencing a concerning skin issue after swimming, particularly with the appearance of a red, painful bump on your vulva. Based on your description, it could potentially be folliculitis, which is an inflammation of the hair follicles. However, there are several other possibilities to consider, including infections, irritations, or even allergic reactions.

Folliculitis can occur when hair follicles become inflamed, often due to bacteria, fungi, or irritation from friction or chemicals. In swimming pools, chlorine and other chemicals can irritate the skin, especially if there are any micro-abrasions or if the skin is already sensitive. Additionally, if you were on your menstrual cycle during your swimming session, it could have contributed to the irritation or increased susceptibility to infections.

Another possibility is a yeast infection, which can thrive in warm, moist environments like swimming pools, especially if you were not fully dry after swimming. Symptoms of a yeast infection can include itching, redness, and the presence of bumps or lesions. If the bump is painful and accompanied by other symptoms such as unusual discharge, it may indicate an infection that requires medical attention.

Here are some steps you can take to address the issue:
1. Keep the Area Clean and Dry: Gently wash the area with mild soap and water, and ensure it is thoroughly dried afterward. Avoid using harsh soaps or scented products that could further irritate the skin.

2. Avoid Irritants: Refrain from using any products that could irritate the area, such as scented lotions, powders, or tight-fitting clothing.

3. Monitor Symptoms: Keep an eye on the bump. If it becomes increasingly painful, shows signs of pus, or if you develop a fever, it’s essential to seek medical attention promptly.

4. Consider Over-the-Counter Treatments: If you suspect folliculitis, topical antibiotics or antifungal creams may help. However, it’s best to consult with a healthcare provider before starting any treatment.

5. Consult a Healthcare Provider: If the bump does not improve within a few days, or if you have any concerns about the possibility of an infection, it’s crucial to see a healthcare professional. They can provide a proper diagnosis and recommend appropriate treatment.

In summary, while it could be folliculitis, there are several other potential causes for the bump you are experiencing. Given the sensitive nature of the area and the possibility of infection, it’s advisable to consult with a healthcare provider for an accurate diagnosis and tailored treatment plan. Taking care of your skin and being mindful of any changes is essential for maintaining overall health and well-being.
