Hi all: I have a friend who was asking me about a mom she's working with who's experiencing uterine pain. 3rd baby, 7 mos, brfeeding well. Mom's on synthetic thyroid, being monitored carefully. The pain has been off & on since baby's birth until a couple weeks ago when it was almost constant--less in the morning, increasing throughout the day. Saw OB who did a transvaginal ultrasound and exam and found nothing. Pain got worse after said exams. Could this be related to hormones of lactation? No Hx of surgeries or other uterine trauma. Vag deliveries, uncomplicated. Any & all thoughts are welcome! TIA Nancy
