Oh, R., how I feel for your son. I agree with the mothers here, you are passing it back and forth whether you are experiencing it pain or not. I felt the pain and soreness, but never creacked open as some mothers have told me about. I don't remember too much what I did for my second son. I remember putting something on the Q-tip and rub it on the inside of his mouth and putting some on me and may have been purple, can't remember. If the pediatrician isn't doing anything, contact your OB midwife and see what they suggest for you to use while nursing. Sorry I can't remember too much what the name was or anything. I just remember that I was soooo sore and it hurt and burned while he nursed and I didn't not enjoy nursing as I did with my third because I had other problems after the thrush and yeast infection healed up. And he is the closest to me, too.
