My daughter is 4 weeks old and my nipples are healed, no visible cracks or bleeding but they are burning, literally almost like they are on FIRE!! It is awful. The burning sensation feels like it is in my muscle too, like behind the breast. I nursed my first daughter until she was 2 and I had mastitis twice early on and it doesn't feel the same as that did. On one side it hurts so bad to nurse I can hardly stand it. I do use breast pads so my milk doesn't leak, I wonder if I have set myself up for thrush? Does thrush require medical intervention or can I treat it on my own? And btw, my daughter doesn't seem to have any spots in her mouth that is why I wonder if that is what it is....any thoughts?
