I have an issue regarding bad odour in under arm. My under arm smells horrible since 6 months. Before that I did not have these problem. I used to use deodorant and sometimes talcum powder. Even before 6 month without deodorant it does not smells. But these days I can not use any because after using within half an hour I get itching in my under arm. The smell is so horrible that when I use soap the foam also turns to smell bad. sweating is an issue for me. I swet a lot. When I swet more the smells become more horrible and when there is no swet still it smells.
