Are you wokring from home, when before you were working in an office? Could be something simple like the position you're in for most of the day causing some tightness further along the kinetic chain.
craporama - yes! i used to commute on the bike to work (and sit all day in the office) now i just roll out of bed and sit all day at my desk, with a run at lunch or post-work (usually the latter) and long rides at the weekend - my riding has been totally unaffected ........
