Labial Swelling: Causes, Symptoms, and Treatment Options

Labial hypertrophy

Hello doctor, on the second day of my menstruation, my labia minora became swollen and itchy, but urination was painful.
Later, my mother found out.
She works at a hospital and took a look, saying it was serious because my labia minora were completely protruding.
She applied diluted iodine to it.
The next day, what was originally itchy became painful.
My mother took me to see a gynecologist in the afternoon, who said I had an allergy to sanitary pads.
He prescribed medication for me to take and a topical treatment, which helped a bit.
Later, when the medication ran out, my mother got a different prescription from another doctor.
I am taking Acyclovir and applying a strong topical ointment.
Doctor, what exactly is my condition? What medication should I take?

It is likely an allergy to sanitary pads.
Sometimes, antihistamines may be needed to reduce swelling.
Also, remember to switch to a different brand of sanitary pads next time.

More Info

Labial swelling, particularly in the context you've described, can be attributed to several potential causes, including allergic reactions, infections, or irritations. In your case, it seems that the initial symptoms of itching and swelling of the labia minora (the inner lips of the vulva) were exacerbated by the use of sanitary pads, leading to a diagnosis of an allergic reaction.

Causes of Labial Swelling
1. Allergic Reactions: As your mother suggested, an allergy to materials in sanitary pads (such as fragrances, dyes, or the pad material itself) can lead to localized swelling, itching, and discomfort. This is often referred to as contact dermatitis.

2. Infections: Conditions such as yeast infections or bacterial vaginosis can cause swelling and discomfort in the vulvar area. These infections may also lead to symptoms like burning during urination, which you mentioned experiencing.

3. Irritation: Other irritants, such as soaps, lotions, or even certain fabrics, can cause similar symptoms. It's important to consider any new products you may have used recently.

4. Hormonal Changes: Hormonal fluctuations during your menstrual cycle can also lead to changes in the vulvar area, including swelling and sensitivity.

Symptoms
The symptoms you've described—itching, swelling, and pain during urination—are common in cases of allergic reactions and infections. The fact that your symptoms worsened after using a specific product (the sanitary pad) supports the idea of an allergic reaction.

Treatment Options
1. Avoidance of Irritants: The first step in treatment is to identify and avoid the irritant or allergen. If sanitary pads are the cause, consider switching to hypoallergenic products or using menstrual cups or period underwear.

2. Topical Treatments: The medication prescribed by your doctor, such as the "強力施美藥膏" (likely a topical steroid or anti-inflammatory cream), can help reduce inflammation and alleviate symptoms. It’s essential to follow the application instructions provided by your healthcare provider.

3. Oral Medications: If your doctor prescribed oral medications, they may be aimed at reducing inflammation or treating an underlying infection. Ensure you complete the full course of any prescribed medication.

4. Hygiene Practices: Maintaining good hygiene is crucial. Use mild, unscented soaps and avoid douching or using perfumed products in the genital area, as these can exacerbate irritation.

5. Follow-Up: If symptoms persist or worsen despite treatment, it’s essential to follow up with your healthcare provider. They may need to conduct further examinations or tests to rule out other conditions, such as infections or skin disorders.

Conclusion
In summary, your symptoms of labial swelling and discomfort are likely due to an allergic reaction to sanitary pads, but other causes should be considered. Treatment typically involves avoiding the irritant, using prescribed topical and oral medications, and maintaining proper hygiene. If your symptoms do not improve or if you have any concerns, please consult your healthcare provider for further evaluation and management.
