I had my little guy 2 weeks ago and have been EBF. Tonight I woke up and my left breast is tender and sore by my armpit and down below it. I've nursed on that side twice since and it hasn't seemed to help much. It doesn't look red (yet) and I don't have a fever or aches or pains. Any advice on how to relieve some of the pain? I'm a first time mom, so not sure of any of this stuff. Thanks for the help!
