In case of vaginal injury, you should go to the hospital to find out the cause of the injury and the site of injury for treatment as follows: 1. The common site of injury is the vaginal opening because the vaginal opening is composed of vaginal mucosa, which is a very delicate tissue and is sensitive to external stimulation, especially if you use too much force during intercourse, which can lead to damage to the vaginal mucosa. In this case, you can use local medication, such as anti-inflammatory drugs, and gauze compression to stop bleeding. 2. The damaged area is the vaginal fornix, which can cause heavy bleeding. If the bleeding decreases, the gauze can be removed and the bleeding area or the damaged area can be checked for repair. If there is no further bleeding or the damaged area is relieved, there is no need for further vaginal compression and natural healing can be awaited.
