[36F] With sudden onset of painful vaginal blisters

What might be happening

Based on the information you have provided, here are some possible explanations for your symptoms:

• Friction or Irritation: Given that you wore jeans and underwear for most of the day and had intercourse last night, the bumps could be due to friction or irritation. This is especially likely if the area was already sensitive from shaving a week ago.

  • Treatment: Typically, this type of irritation can be managed with over-the-counter topical treatments like hydrocortisone cream to reduce inflammation and irritation. Keeping the area clean and dry is also important.

• Folliculitis: This is an inflammation of the hair follicles, which can occur after shaving. Even if you don't see a black dot indicating a hair follicle, the irritation from shaving can still cause folliculitis.

  • Treatment: Warm compresses can help soothe the area. Over-the-counter antibiotic ointments may also be useful.

• Herpes Simplex Virus (HSV): Although you mentioned no recent exposure to new sexual partners, HSV can sometimes present as clear, blister-like bumps that are painful. This is less likely given your history, but it's still a possibility.

  • Treatment: Antiviral medications are typically prescribed for HSV. A healthcare provider can perform tests to confirm this diagnosis.

• Contact Dermatitis: This could be a reaction to a new product, such as soap, laundry detergent, or even a lubricant used during intercourse.

  • Treatment: Identifying and avoiding the irritant is key. Over-the-counter antihistamines and topical steroids can help alleviate symptoms.

What you can do

While it's important to consult a healthcare provider for a formal diagnosis and treatment plan, here are some steps you can take in the meantime:

1. Keep the Area Clean and Dry: Gently wash the area with mild soap and water, and pat it dry. Avoid using any harsh or scented products.
2. Avoid Tight Clothing: Wear loose-fitting, breathable clothing to reduce friction and irritation.
3. Over-the-Counter Treatments: Consider using a topical hydrocortisone cream or antibiotic ointment to reduce inflammation and prevent infection.
4. Warm Compresses: Applying a warm compress can help soothe the area and reduce discomfort.
5. Monitor Symptoms: Keep track of any changes in your symptoms. You can use MDandMe to journal your symptoms, track progress, get insights, and share longitudinal medical notes with your provider.

What you should look out for

Seek medical attention if you notice any of the following:

• Increased Pain or Discomfort: If the pain becomes severe or unbearable.
• Spreading Redness or Swelling: This could indicate an infection.
• Fever or Flu-like Symptoms: These could be signs of a more serious infection.
• Unusual Discharge or Odor: This could indicate a bacterial or yeast infection.
• No Improvement: If your symptoms do not improve or worsen over the next few days.

Remember, while these tips can help manage your symptoms, it's important to consult a healthcare provider for a formal diagnosis and appropriate treatment.
