Hello, I have a very delicate question... after childbirth, there were some sensitive knots... who treated them? It's embarrassing to go see a doctor, somehow... We also have a newborn baby, we will be only a month old... and I am afraid to leave this problem unattended... and there is another problem, my belly area hurts (soft tissues) or how else to call it? I don't know how to name it properly.
