Girls, help! I gave birth two days ago, they said it was just a tear, but for two days now I can't go to the toilet even a little bit, what to say about big ones, it's really painful, it hurts so much, I cry, I try to go, but it starts to sting so badly that you can take any action? Any ointments, medications.
