I am currently nursing a 14-month-old. We nurse about 3 times a day (morning, afternoon, and before bed). For the past 5 days, we had been on vacation, so I was nursing him more often because he wouldn't go down for naps on his own, and he woke up more often at night. Therefore, I was probably nursing about 7-8 times per day during this time.
This brings me to my current situation. It started with both nipples being sore upon latching. My son is a gymnast when it comes to nursing, so I thought maybe it had something to do with that. Then, yesterday, my whole breast started to hurt--just one. It actually hurts more to the touch than while nursing. I don't feel any lumps, so I don't think I have a plugged duct. It was so sore last night that I couldn't even sleep on that side.
Any ideas what might me going on? I've nursed for 14 months and only had a milk blister way back in month 2, so I've been relatively lucky with nursing-related pain and problems.
