Check your footprints in the snow!
If your prints are particularly turned out (i.e. you walk like a duck!) it could indicate that you have a tight piriformis muscle.
Tightness in the piriformis muscle can put pressure on the sciatic nerve, which can cause back, buttock and leg pain. But, not to worry! A massage and a few stretches should help to remedy that!
