Vaginal sensation like blowing bubbles is medically known as pussy blowing. These conditions are mostly seen in women after vaginal delivery and are especially noticeable during intercourse. The causes of pussy blowing are related to vaginal laxity and lack of recovery of the pelvic floor muscles after childbirth. For women who have just given birth, they can go to the postpartum rehabilitation department of the hospital 42 days after delivery for pelvic floor muscle rehabilitation, where they can do vaginal dumbbells or electrical stimulation to contract the loose vaginal muscles. If women who have not just given birth have the sensation of vaginal bubble blowing, it may also be vaginal inflammation and infection with gas-producing bacilli. Most of them will be accompanied by vaginal burning pain or vulvar itching, you can use red nucleus lotion or use cleansing lotion to wash your vulva. If the effect is not good after washing, you need to do a leucorrhoea test and according to the result of the leucorrhoea test, you can use vaginal suppositories for treatment.
