Chafing

Chelsea
Okay I need some help here. For a little bit now Ive been experiencing chafing. And its only in one place. This part is the part that I need help with on how to keep it from recurring. Its happening right where my butt and thighs meet and where my labia meet my butt. It went away on its own for a few weeks but its back again. Is there any way I can stop this from happening and any way I can make it stop quick. Im not over weight. But I do work a lot. And that requires me to walk constantly. Any ideas and tips would be so very much appreciated.
