I am a size 16 woman with large breasts. I have very painful irritations with large wart-like bumps under breasts and at panty line. I have tried yeast products and Silver solutions. Nothing is helping. I live in the desert, but this has been through late winter and early spring. I have gone to oversized underwear to help the irritation at thigh level, bought different kinds of underwear. I don t know what else to do.
