During the 1st visit, the patients will be assessed for pain and episiotomy wound. The cryotherapy group will include 12 postnatal women. This group will use a bag of ice packs applied to the perineal region. The ice pack will be sealed in a plastic bag and wrapped with one layer of thin cotton tissue so that the skin of the participant will not be in direct contact with ice, which could cause discomfort. During the intervention, the women will be asked to remove their underpants and hygienic pads and remain in the dorsal recumbent position during cryotherapy that lasts 20 minutes. This procedure will be done twice a day for seven consecutive days

The infrared group will include 12 postnatal women they will be encouraged to place an infrared lamp at a distance of 45 cm from the perineum and the heat produced with 230 volts for twenty minutes. But the mother is checked after the first five minutes to make sure that she is not being burned. The researcher will demonstrate for each woman how to use an infrared lamp, and it will be followed by re-demonstrations and discussions. These procedures will be carried out in the morning and evening for seven consecutive days. The researcher gives the infrared lamp device to each woman and then restores it after completion of the study

The NPRS is a segmented numeric scale in which the respondent selects a whole number(0-10 integers) that best reflects the intensity of his/her pain. The common format is a horizontal bar or line. NPRS is anchored by terms describing pain severity extremes.

The REEDA scale is an observational check list used for assessing perineal healing.The acronym REEDA is derived from five components: Redness, Edema, Ecchymosis, Discharge and Approximation of the wound edges.Each component takes a score ranged from 0 to 3. Higher score indicates poor wound healing while lower score indicates good wound healing.The total score of REEDA scale was categorized as follows:

0 to 2 - Healed.3 to 5 - Moderately healed.6 to 8- Mildly healed.9 to 15 - Not healed.
