2.5 weeks postpartum and I have had an intense pain/pressure just below my chest since giving birth. The pain intensifies when standing and especially when holding my son. I have tried carrying him in our infant backpack carrier to run errands and cannot do so because I get out of breath and dizzy from this pain. I figure it is probably just my body readjusting as my uterus returns to a normal size, but have talked to other postpartum moms who have not experienced this symptom.
