I have an itchy sensation starting from the right side of my left breast spanning across my chest underneath my right breast. first starting feeling itchy about a week ago. At first it was red and looked like a rash, now the rash is barely noticeable but still itchy. any thoughts as to what thi sis?
Hi, I have read your query & understood your concern.  The itchy rash under breast is common in fat, diabetic,pendulous large breasts.  In such conditions, there is a lot of sweating, the moistness helps breeding of bacteria/ fungi, thus a skin infection develops & itching increases.  Simple sweating can produce prickly heat rash (Cleanliness+coolness+ talcum powder help.  Fungus infection needs to be diagnosed by skin specialists & treatment accordingly. Allergy to material of under garments-stop use of the allergen/ use cotton garments. Bacterial rash has pus filled tubercles-need antibiotic.  Please consult a skin specialist for diagnosis & advice.  Thanks
