I get a stinging feeling which I'm assuming is my breasts filling with milk as it happens close (ish) to feeding times and I also get some random deep pains and occasional stinging nipples too. I've had thrush before and it's not like that (though part of the reason I'm asking is that I'm terrified of developing an infection again). Given all that goes on it makes sense that some breast pain is normal but just trying to figure out what exactly! How do you know what is normal and what isn't? Really interested in hearing other people's experiences.
