How do you know if your breast is infected? I heard it can really make you sick and may stop your breast feeding? I'm pretty sore on the right side, but more towards my ribs. I thought it was just a clogged duct, but now I'm not sure. If it is just a clogged duct, how to do you unclog it? I've tried the shower and rubbing it out with hot water while pumping...or is it still sore even after it pops? Don't know what to think, help!
