The itching on both sides of the urethra is caused by inflammation, which may be caused by urethral or vulvovaginal inflammation, and is related to unclean sexual contact or low local resistance to infection germs. If the itching is accompanied by increased discharge on both sides, it is vaginitis. If there are no other symptoms, you can use gynecological lotion to clean the area or use bitter ginseng lotion to clean it and then apply anti-infection creams, such as erythromycin ointment and fluoxetine ointment, etc. Symptomatic treatment for 3-5 days can relieve the symptoms. You can also take antibiotics for treatment, pay more attention to personal hygiene, wash your vulva with water every day, change your underwear regularly to avoid infections caused by bacteria, avoid sexual intercourse during the medication period, quit smoking, quit drinking, and avoid stimulating food.
