Hello, my armpit felt like I had a small cut on it but when I checked there was nothing there no cuts or lumps, and there was no pain yesterday, it hurts when I move my arm (it only hurts on my left armpit) when I touch it, it doesn t hurt it. it has only been a couple of hours but it still hasn t gone away. I also know that I didn t mess with my armpit the day before, there is also no redness on my armpit.
