I don't know about the bad breath part. There was someone on here who cured bad breath with clay. Check the posts. However, the other parts you are describing are areas of the body where skin is in contact with skin or can be trapping sweat and dermatophytes. Do the breast and groin areas itch or show a slight rash at all? A friend of mine is in medicine-derm. and if you have tinea or candida skin infections they can stink. You can get tinea of scalp as well and it can spread from scratching scalp to other areas of body. Have you seen your Doc for these areas?
