I have no idea where this came from or what caused it, but on Monday this week I felt a pain in my left armpit. I had no idea what it was, so I went to look in the mirror and it looked like a burn going around the outside of my armpit ( almost making a half circle like shape). Fast forward to today, now the are where the pain is located is darkened and if I press on it there is clear water like liquid that comes out.

My guess was that the old spice deodorant ( which is not unusual that it burns a little bit when I apply) caused this. I honestly don't know . I have been putting neosporin on it for the past couple of days with no luck.

What should I do ?? This thing HURTS!

No I did not shave at all in that area
nor did I wax
