Vaginal pain during intercourse. First of all, the most common cause in the clinic is due to inflammation of the vaginal mucosa. As the vaginal mucosa itself has inflammation, friction during sex will lead to localized pain, so it is necessary to actively treat vaginal inflammation. After the vaginal inflammation is cured, the painful symptoms will disappear naturally. Secondly, if vaginal pain occurs during intercourse, the pain may also be caused by decreased ovarian function, decreased estrogen levels, decreased vaginal secretions, and vaginal dryness. To relieve the pain, you can use an adult lubricant, which can be inserted into the vagina before sex. You can also use estriol ointment into the vagina to relieve the vaginal pain. It is also recommended to have a gynecological examination once a year, an ultrasound to check the thickness of the lining of the uterus, cervical cancer screening, and a breast examination. There is no problem before you can use estriol ointment for treatment. Also during intercourse, if the pain is due to inflammation can be treated by inserting a diazoxide suppository in the vagina.
