Comparing three duration times of cryotherapy in pregnant women for relieving pain from perineal trauma after birth

This study compares three different lengths of time for applying an ice pack (cryotherapy) to the perineum (the area between the birth canal and the back passage) to relieve pain after a vaginal birth. Pain in this area is very common after childbirth, especially when there was tearing or stitching. The study aims to find the most effective duration for ice pack treatment.
