Vaginal pain is a common phenomenon after mid to late pregnancy for the following reasons: a. The enlarged uterus compresses the pelvic floor, causing mechanical compression of the pelvic floor nerves, resulting in vaginal pain. The enlarged uterus compresses the inferior vena cava, causing obstruction of venous return and resulting in vulvovaginal edema and varicose veins, resulting in vaginal pain. The enlarged uterus compresses the pelvic floor musculofascia, which is overstretched and causes damage, resulting in aseptic inflammation that stimulates the nerves and pain, and the pelvic floor muscles are compressed, resulting in vaginal spasm and vaginal pain in sensitive pregnant women. Pregnant women can elevate their hips at rest to alleviate the compression and edema to relieve the symptoms.
