Juat noticed this tonight and trying not to panic too much. I do have a telemedicine appointment on Thursday for another issue so will address this then, too.

Basically, I noticed that under my right armpit seems puffier than under my left. I can't say it's a definable mass or even a lump but it's just like it is puffier. Maybe feels a bit like some type of muscle under there is more pronounced? I don't know how long it has been like this and I don't think I am explaining it very well.

Anyway, I am freaking out thinking it is the big C.

I just had a baby in July and have two other kids. I am currently breastfeeding and don't know if that contributes?

Either way I feel so scared now. I'd this normal? Anyone else have something similar? Of course stressing about it has given me a headache so that's another thing for me to worry about.
