Patient's question:

I have an itchy lower body, and my underwear is always yellow. What's going on? Which medicine is good for itchy lower body with a bad smell and yellow liquid?

Doctor's answer:

In your case, it may be bacterial or fungal vaginosis. You can use the decoction of Sophora flavescens or Berberis vulgaris to rinse and treat it, which can be somewhat effective. Both Sophora flavescens and Berberis vulgaris have anti-inflammatory and antifungal effects, but the latter should not be taken internally. If you haven't taken any contraceptive measures, there is a possibility of pregnancy. You can use early pregnancy test strips to check and confirm whether you are pregnant. Timely observation and treatment are necessary.
