I keep getting these clear puss filled bumps under my boob. At first I thought it was from a heat rash, but then I ended up with 3 of these bumps that became red, swollen and painful. 1 seems to have gone away on it s own, the other 2 formed a small hole and drained out. What drained out was clear puss like, with a little blood and it smelled bad, what could these bumps be? and what could be causing them?
