Effectiveness of transcutaneous electrical nerve stimulation for painful postpartum uterine contraction during brestfeeding

This study is testing whether TENS (transcutaneous electrical nerve stimulation) can relieve the painful uterine cramping that breastfeeding mothers experience soon after delivery. When a mother breastfeeds, the body releases hormones that cause the uterus to contract, which can be quite painful — especially for women who have had more than one baby. TENS uses mild electrical pulses on the skin to reduce pain.
