Am bf ds, who's now 13 weeks. Right breast started feeling painful yesterday, almost like a pulled muscle, but nipple was fine and ds feeding no problem, with no pain. This afternoon, I started to feel a nasty pain in the side of the right breast and under the armpit, and that part of my breast felt very hard. DS was asleep, so I expressed and got 5fl oz straight off (this isn't an unusual amount - I express more than that every morning - but I don't usually express at this time of day at all). He hasn't missed any feeds and I can't think of any reason why I'd be engorged on that side. DS has since had a feed, which was painful when latching on and uncomfortable throughout. I had mastitis when he was a couple of weeks old, though that started with a huge red patch on my breast; I can't see anything like that this time. But I think (may be imagining it now!) my right breast feels a bit hot and I'm also feeling generally a bit hot and cold. Back is killing me, too, but perhaps that's just from lugging ds about? Can't carry him on the right side at the moment as too sore. Is it mastitis? What should I do?
TIA
