i'm a 22 yr female who has been active her whole life (gymnastics, soccer, pole-vault, cross-country, wrestling, hockey, mtn. biking, skateboarding, snowboarding, in-line, rock-climbing) after graduating college i found a job and use my road bike for my commute to work everyday (10-20mi/day) not much. i'm a terrible procrastinator and i usually end up sprinting the 6 mi across DC to work. anyway, i've noticed a kind of numb sensation under my thighs and especially when i'm seated. some times i feel it in my arms too, though not often. so what's the problem, do i need a new saddle? more rest? more time to get to work? should i stretch? thanks.
