In the past month, I've been experiencing severe lower back pain, a heavy and bloated feeling in my lower abdomen, and excessive white discharge. Please ask: What are the reasons for vaginal itching in women?
---
Doctor's answer:
There are several reasons that can cause female external genital itching, such as vulvar dermatitis, vulvar eczema, and vulvar malnutrition. In addition to vaginal inflammation, vulvovaginal candidiasis, bacterial vaginosis, trichomoniasis, mycoplasma, and chlamydia infections, all of these can lead to external genital itching. Additionally, if you have diabetes, the stimulation of urinary sugar can also cause external genital itching. It is recommended that you pay attention to personal hygiene, and you can use a liquid for cleaning together. If necessary, medication treatment is required.
