Attachment on one side is really painful at the moment and then when dd is drinking I get like a pain that kind of radiates upwards to underneath my arm. It hurts a lot and continues the whole length of the feed. It's not my usual symptoms of thrush but I'm not sure what else it could be. The only other thing I've noticed is when dd pulls off that nipple is a really really dark purple. In a few seconds it goes back to a normal colour. So does it sound like thrush?? Whatever it is, it freaking hurts. Sometimes that boob aches a little bit in the nipple too.
