I had some discomfort in my right armpit tonight, checked in the mirror and saw some redness, and realized that it hurts to touch a lot and it feels like there is a little pimple/node there. I wasn't shaving my armpit recently and I haven't use antiperspirant. I also don't have any infection that I know of, no fever or anything.
I can't seem to tell if it is hard or soft, my guess would be soft, but it's also not moveable or I think it is not. If it was somewhere else I would guess it's just inflamed pimple but in the middle of an armpit instant thoughts are swollen lymph nodes-cancer.
Anyone had similar things? I am 29y old male btw.
