The hospital doctor said it was vaginitis (without specifying the type) and mentioned it could be a sexually transmitted infection.

Doctor's answer:

Vaginal inflammation is one of the common diseases among women, directly related to personal constitution and hygiene conditions, and there is a certain possibility of recurrence. It is recommended that you promptly go to the hospital for a leukorrhea test and ultrasound examination to determine which type of inflammation it is. Then, symptomatic treatment can be administered. Additionally, attention should be paid to sexual hygiene. The occurrence of vaginitis not only affects the patient's body but also leads to gynecological diseases. Therefore, it is best to undergo a leukorrhea test at the gynecology department of the hospital, identify the cause, and then receive symptomatic treatment. Pay attention to dietary regulation, consuming light and easily digestible foods, and avoid spicy, stimulating, and cold foods.
