Uterine contractions are strongest during labor to help deliver the baby. However, if these contractions continue for a long time with a strong nature and cause a lot of pain, they can cause obstetric complications such as postpartum hemorrhage, heavy vaginal bleeding, etc., endangering the life of the mother.

The perineum is the anatomical area between the urethra, the tube that carries urine from the bladder, and the anus. In women, the perineum also contains the vagina. During childbirth, some women will need to have an episiotomy to help the baby pass through the vagina more easily. However, this also causes postpartum pelvic pain, and some measures are needed to help relieve the pain.
