I have a horrible armpit odor problem, I have tried everything it seems like so I bought this and tried it out and it gave me horrible bumps on my armpits, it took forever for them to go away, i was not able to wear anything on my armpits except for Bromi-talc which helped for a few days but stopped as well. I am not sure what to do about my armpit odor problem, it is embarrassing and i just want to find something that works.
