Rash started in armpits then chest hair then belly button
I’ve been a lot more active this summer than usual and sweat a lot. Started noticing this rash in areas where sweat collects a lot like armpits first then chest, belly button and now it’s starting around my neckline. Saw my doctor who thinks it might be fungal but isn’t sure. Wants to start me on Ketoconazole for 10 days and see if it improves. Any idea if he’s right or what it could be?
