Why does itchiness appear after the menstrual cycle?

Ask
Hello doctor. Currently, I have symptoms of itching in the private area, very uncomfortable and when I go to the toilet, I have to scratch to relieve that itchy feeling. The itching time is about 10 days, since the menstrual cycle ends (during my period, I change tampons regularly, morning, noon, and night, and last time I used another type of tampon. compared to tampons I usually use).
At first, I didn't feel much itching, but after that, I kept itching continuously from morning to night, I used a cleaning solution to wash the private area but still didn't see any signs of reduction. I'm 23 years old and still haven't had sex. Can you help me determine the cause of the itching and how to treat it? My mother told me to go to the doctor but I was very shy. Seek medical advice. Thank you!

Hello. My case has not had sex, there is itching after menstruation. After menstruation, the vaginal environment changes, there may be vaginal itching, usually caused by fungus. The cleaning solution can only temporarily clean the cause, but not completely.
To determine the exact cause, you should visit an obstetrician. The doctor will take a sample from the outside of the vulva when the inflammatory fluid flows out for testing and use the right medicine for the cause.
In your case, you have not had sex, the doctor can use the pill form and put it right outside, or use the drug for the whole body.
Thank you for your question to Vinmec Health System. Best regards.
