If there is a round ball in the vagina you need to go to the hospital for a gynecological examination to be able to observe at a glance exactly what is going on. There are several possibilities to consider in this clinical situation: first, the patient feels a normal cervix, the vaginal part of a woman’s cervix, which can be touched from inside the vagina. The cervix is round and bulbous when touched, has a tougher texture, and the patient is not uncomfortable. Secondly, the patient has prolapse of the uterus and cervix, so the patient can touch the round ball-shaped substance when washing the vulva or vagina, and most of the time there is discomfort such as lower abdomen and back pain, and it is also accompanied by increased leucorrhea. If the prolapse is severe, the uterus or cervix may prolapse outside the vagina. Thirdly, the patient has vaginal wall cysts, submucosal fibroid prolapse or cervical fibroids, so the patient is able to touch the round ball-like substance. Depending on the situation, the patient may have a feeling of vaginal swelling or irregular vaginal bleeding.
