I have this exact same rash. I've had it for years now. I hate it. I itch all the time and then it bleeds and stings. After trying all kinds of creams, including an RX from my diabetes Dr., I found this stuff on Amazon. It helps so much! I use it morning and night. Im not sure why this works the best out of everything but its a lifesaver. It isn't taking the rash away it is only helping with the itchy, burning, odor, etc. I wish I could find something to take it away for good.
