I'm currently EBF my 13 week old daughter and all has gone well so far. This morning I woke up with an incredibly sore right boob, definitely not engorged and can't feel any lumps in it to massage out. No idea what's happened but it feels like someone has punched it. She's been feeding as normal from it. Doubt it's mastitis as I feel absolutely fine, just wondered if anyone had any similar experiences?
