Saddle sores are unpleasant, but manageable. I wouldn't take a week off because of one, actually I get them usually when I ride an indoor trainer due to excessive sweating (I know, TMI).. I find that if I just clean the area good, and keep it dry, it'll heal on it's own in a day or two.

As for chamois cream, this stuff is great, and at $4.50 a jar, cheap.
