Just recently, maybe since last week, my left armpit smells rancid...while the right armpit has no odor at all. I've washed and scrubbed with antibacterial soap, but infinite showers could not rid me of this smell. It's not even the typical BO sweat smell...it smells...bitter and makes me nauseated. I've never smelled anything like it. It is not going away no matter how much deodorant I apply, I even tried not using deodorant at all. What gives ?
