I've noticed it really hurts when LO nurses on the left side for the last 2/3 days. I thought it might just have been a bad latch, but tonight I actually see a white dot on my nipple. I thought it might be a plugged duct, but googling seems to indicate a milk blister. Anyone have experience with these? Do they resolve on their own? It's so painful! I'm also traveling at the moment so don't have access to Epsom salts, grapefruit seed extract, and other things recommended for this condition. Any help or experience with this appreciated!
