There are several reasons for vaginal pain during intercourse: 1. If the force is too strong during intercourse, it may stimulate the vaginal wall, resulting in various phenomena such as vaginal pain and vaginal bleeding. 2. If women suffer from gynecological diseases, such as vaginitis and pelvic inflammatory disease, there is already inflammation that stimulates pelvic congestion during intercourse, thus resulting in vaginal pain. It is recommended to go to the hospital for physical examination to see if there are gynecological diseases, and anti-inflammatory drugs can be used for symptomatic treatment. 3. There are also other diseases that may cause it, such as malignant tumor or other systemic diseases. When these diseases appear, they may lead to inflammation and a series of abnormal reactions, which may cause various symptoms such as vaginal pain.
