Hello! LO is 2 weeks old now. For about a week I've have a lump under my left underarm. It's tender to touch but not red or warm. I thought maybe it was a plugged duct and did warmth, and massage which didn't help. So I kinda forgot about it. But now a week later it is still there? Anyone had anything similar? I'm having no issues nursing and I've never gotten a plugged duct with my older daughter. Thanks!
