Hello mommies! Two months ago I had a cesarean section. I had a month of recovery after the surgery. They did an ultrasound inside and said everything was fine, healing well. Now, on the second month, it hurts at the bottom where the incision is inside, with spasms especially at night, that I can't sleep. Can you tell me what this could be and has anyone else experienced this after a cesarean?
