I have being sitting down alot today, though not solidly for hours on end..
I have a pain from my left hip to my toes, and it's really starting to drive me up the wall!!

Has anyone else experienced this?
Is there something I should be doing?
Walking on it seems to hurt more
It sounds like sciatic nerve pain - you can get some physio to help relieve the pressure on the nerve. In the meantime, heat packs on your hip may help where the pain is worst.
