Yeah sitting just is not good for us, It's an unatural position so causes us issues.
I have piriformis issues which are exasperated from driving with my wallet in my back pocket.. I can now even feel when its twisting me and try not to put it there anymore.
A good sports physio will look at all this though and not just your sporting history and work out what is going on.
