Postpartum uterine contraction abdominal pain is mostly seen in menstruating women, usually appearing 1-2 days after delivery, and can be relieved or disappear on its own after 2-3 days, and generally does not require special treatment. If the number of cesarean sections is higher, the duration of postpartum contraction pain will be longer. In addition, the increased secretion of reflex oxytocin during breastfeeding will also aggravate the abdominal pain. If the pain is mild, you can change your sleeping position to side sleeping and avoid lying down, standing for a long time or sitting for a long time to reduce the pain. Mothers can massage and apply hot compresses to the abdomen to temporarily relax the uterine muscles and relieve pain. If the pain is severe and intolerable, you can take antipyretic and analgesic drugs under the guidance of professional obstetricians and gynecologists for symptomatic treatment.

Regular checkups should be conducted to monitor your recovery, and you should seek medical advice if you are experiencing any serious discomfort.
