OMG go to the dr!! if it is torn they will stitch you up again
I've never had that happen to me but it's always better to get it checked out than just dealing with it. Yes you could end up with an infection if it reopened. I'm not a doctor but I'm sure if that is what happened, he would probably have to restitch you, depending on how bad the tear is. Call your doctor, don't let it get any worse. You'll feel better for it and I'm sure your husband will too...lol! Good luck!
