I have a chronic tear in my gluteal fold. I have seen a dermatoligist. She has treated it w/multiple creams w/no success. She thinks its due to sweating & perspiring, so we've discussed methods to keep the area dry. Currently using Balmex & Zeazorb powder. However, when the area reopens, I do not use powder. Any other suggestions? It burns, sometimes bleeds & will not heal.
