What causes a red rash under the arm?
Patient: I have a red rash under my arm. Last time I had it, I was pregnant with my daughter & gestationaly diabetic. I am now neither diabetic nor pregnant. A doctor said then that the rash was related to kidney function - or the lack thereof... Just wanted some insight? Doctor: Hello,Thanks for the query,Red rash under arms can be a fungal infection.The area of skin folds is very moist and is prone to develop these infections.Treatment can be with oral antifungals as well as with topical antifungals.Various antifungal powders like candid are available.These can help reduce the moisture as well as control the infection.Please meet a dermatologist for exact diagnosis.Let me know if you have any other doubtsThank you
