Thanks for the answer. I am just worried, b/c I walk all day. I did take 2 weeks off, but I don't want anything to irritate the area when I do return.

Sue,
The cotton should stay in place when you'r walking. I've had a couple of cotton balls go astray... but then again, I'm a guy and I wear boxers.
I think you made a wise choice taking two weeks off. When you do return to work, the cotton will help to keep things dry and irritation free.
Just think, 12 more days and you will be home free! :D
