What is the reason for persistent itching after treating mold?

Patient's question:

Duration of illness and persistence: 2 months
Doctor, I would like to ask: I have had two induced abortions before. Before the second one, I had a fungal infection, which was treated and cured before the procedure. The second abortion was performed about half a year ago. However, I have been itchy ever since. I went to the hospital for a vaginal discharge test, and it has been normal every time, even after multiple tests. I also tested for mycoplasma and ureaplasma, and the results were normal too. But why am I still itchy? What should I do?

Doctor's answer:

Hello: If the color and texture of leukorrhea are normal, you can use Jie'eryin to clean the vulva. Pay attention to hygiene.
Vulvar itching is a symptom that can be caused by various factors. Local causes include special infections (such as candidal vulvovaginitis, trichomoniasis, pubic lice, scabies, pinworms), chronic vulvar dystrophy, drug allergies or chemical irritation, poor hygiene, and skin diseases. Patients with chronic conditions such as diabetes, jaundice, leukemia, vitamin A deficiency, or vitamin B deficiency also often experience vulvar itching. In some cases, there may be no obvious local or systemic causes, and it may be related to psychological or mental factors. Patients with this condition should identify the cause and treat accordingly.
[Prescription]
1. Pay attention to menstrual hygiene, change menstrual pads frequently during menstruation, and clean them regularly.
2. Keep the vulva clean and dry. Avoid hot water washing or soap scrubbing.
3. Avoid indiscriminate or excessive use of medications, scratching, or local friction.
4. Avoid alcohol and spicy foods. Do not eat seafood or other allergenic medications.
5. Do not wear tight undergarments. Underwear should be loose, breathable, and preferably made of cotton.
6. If there are any broken areas or infections locally, you can soak with a 1:5000 potassium permanganate solution (add a small amount of potassium permanganate powder to warm water until it turns a light red color—do not make it too concentrated). Soak for 2 times a day, each time for 20–30 minutes.
7. Seek medical attention to check for candidiasis or trichomoniasis. If present, treat them promptly instead of using over-the-counter "itch relief" solutions.
