Quick question...my 3 month old is killing my right boob. Is it possible from him pulling back on nipple to "pull a muscle"? It's a shooting pain. Only hurts sometimes when he nurses. I hold his hand so he can't push back.i don't think I have thrush. I have this habit of us going to sleep side nursing... Sometimes with either boob in his mouth.. Can that create thrush? Sometimes my nipple is white for about 30 seconds once he pulls off. If it was a latch problem, wouldn't it be on both boobs? It only hurts during the nursing time..sometimes.
