I am so pleased to have an opportunity to answer a question that has our list
mother stumped, that I will even use proper punctuation.

Yeast under the breast can occur just as easily as other warm moist body
areas.  I have heard of it happening after shaving during antibiotic use
(causing yeast in the armpit). Maceration can lead to yeast in any area where
skin rubs other skin (C/S scars are prime sites if you are not thin). Of
course she doesn't have to reduce bathing, just treat it with gentian violet
or the other OTC creams etc. until it goes away, as well as the other adjunct
treatments (acidophilus etc.).
