i agree with nurse(angel) that a proper diagnose can be made only after clinical examination.
i think it may be a fungal infection ,for this you can have an antifungal cream that will solve out this prob,like Ciclopirox olamine ie Batrafen cream, its also available in powder form or solution.
apply Batrafen Cream to affected area (clean dry)twice daily on average and allowed to dry. Treatment should be carried out until the symptoms have subsided (2 weeks in most cases).
if its allergic please you can use some OTC hydrocortisone cream.
when sleeping at night remove your bra when you go to bed so that the area under the breast should have enough air circulation,
keep the area areola clean, (warm water wash )as the sores may get infected.avoid touching with unwashed hands.
Remember Humidification is good but excess may result in fungal infections of skin.
(however if the problem persist please visit your doctor for futher evaluation )
i hope this will help!
