I am currently tandem nursing my 3 1/2 year old (at night and morning only) and my 6 month old. This morning I woke up feeling some pain in my right breast which I thought was engorgement (my 6 month old, who nurses several times at night, sleeps on the other side of me so it's not uncommon for me to wake up with the right side a little engorged.) However, the pain has remained all day. It is only on the outside of my breast (from just outside the nipple over to the rib cage) and it is tender when I press on it. I don't feel any pain unless I am touching it,
I've never had anything like this before - any idea what it could be?
