I've had AN since I was about 8. Its mostly around my neck, armpits, and groin. My mom kept telling me to quit being lazy and scrub myself..only I was. As I got older, I've used all kinds of methods to get rid of those ugly "dirt marks", from exfoliators to metal scouring pads to the point of drawing blood. I really don't know what else to use in short of removing the actual skin. I read that its related to obesity and insulin resistance. i wouldn't really consider myself obese, nor has any of my family ever had diabetes. its really frustrating bc i always have to wear my hair down and turtle necks to cover my neck, not to mention NEVER being able to wear those comfy tanktops. Can anyone recommend any Overthecounter drugs to take for it? or does laser surgery help? I'm so glad to have found this site where I have so many people to relate to!
