Oh Danni you poor thing. Do you have to work, Maybe you should take a fewwdays off and rest and go to the physio etc.

I've never felt the pain your speaking of but I do know what it feels like when your pelvis tightens and you can't move your legs. I got hit by a car 10 years ago and evey now and then it would happen and I just had to wait it out. Luckily it doesn't happen to me anymore (fingers crosssed anyway)
