I'm 11 weeks pregnant and I have a hard lump in my armpit. It's not large, like I'd say about the size of a pencil eraser or the tip of my pinky. It's pretty sensitive to a firm touch and really hurts if I try to squeeze it. I also noticed I've been getting red bumps, almost like large pimples but no white head and not poppable and a bit painful in my armpits as well. I don't shave them every day. Only every few days and I use aluminum free deodorant. I've been using this same brand deodorant for over a year without any issues before. I don't think it's an ingrown hair. I've never had one in my armpit before so I don't think I would all of a sudden get a bunch of them. I'm thinking this lump could be an inflamed lymph node but why would I get that? What would cause it? I'm also still nursing my baby but only for naps and bedtime and I don't think it's my milk ducts. I got a huge swollen milk duct in my arm pit when we first started breastfeeding and the pain feels similar but I just don't know any reason why I would have that now. And it wouldn't explain the other red bumps. Has anyone else experienced this? What was it?
