My cheeks hurt :)

[Helen]

Hi Helen, sure your "burning cheeks" aren't muscle fatigue? You know... "feel the burn"...?

For that i recommend a gentle ride just to ease the muscles a bit...

Well ... I guess I am talking about my muscles but I am pretty sure they are not fatigued but squashed from the not so smoth rides I've made this last week.

Thanks for your recommendation but I sincerely think there is no such thing as "gentle ride" ...
Maybe all I need is to change my sadle ... What kind of sadle should I buy ? Are they all going to fit on my bike ?
