What tests should be done for vulvar itching

Patient's question:

Is urinary retention a symptom of urethritis? The doctor said it's urethritis, or is it kidney problems? Can urethritis cause vaginitis? There's a bump on the outer labia with some itching, and it hurts when touched? The discharge is yellow, is it serious? What tests should be done? Thank you

Doctor's answer:

Hello, there are many reasons for itching, it could be due to an infection, or it might be caused by gynecological diseases. It could also be itchy for no reason at all. Although it's not a disease, if left untreated for a long time, it can easily lead to many gynecological problems. It's important to seek timely treatment. The best option for you is to use traditional Chinese medicine steam baths. Liquid washes are ineffective, while traditional Chinese medicine steam baths are non-irritating and have a very good therapeutic effect.
You should also pay more attention to hygiene and menstrual hygiene. Keep your underwear breathable and avoid using medication indiscriminately.
