My baby is 17 days old and we were doing great but about 2 days ago, my left breast and nipple became very sore, my nipple looked ok, but it sure did hurt and when my milk came down it burns and today when she latched on, I felt like I was going to pass out. So today I started pumping for the first time and that was ok and didn't hurt to pump (just alittle sore) and she took to the bottle. But I am concerned that it is an infection, not just sore nipples. Now my right side is getting sore. Any suggestions, should I see my doctor???
