Vaginal pain after intercourse is considered as vaginal dryness, which is caused by vaginitis, and may also be caused by lack of vitamins, and may be caused by excessive force causing vulvar tearing. If the inflammation is promptly treated with anti-inflammatory drugs, it is best to take vitamin B. Do foreplay during sex to promote vaginal fluid secretion to play a lubricating role and avoid dryness; if the vulva has pain caused by tearing, it is best to locally clean and disinfect with potassium permanganate solution to avoid infection, you can also rub erythromycin externally to promote wound healing; if abdominal pain occurs during intercourse, consider pelvic inflammatory disease. The actual pain is also caused by the contraction of the uterus during orgasm, pelvic inflammatory disease can easily cause abnormal leucorrhea, which can be diagnosed through ultrasound, oral anti-inflammatory drugs or infusion treatment, if the contraction of the uterus is caused, rest for a few hours can be recovered.
