Worried about my rabbit!

[cooksters]

I have a 2 year old Rex rabbit who for the last week has been struggling to walk on his front paws, his back ones are fine.
I've taken him to the vets and after giving him a good check over they can't seem to find anything wrong. They gave him an anti-inflamitry injection as they said they can only treat the symptons. I've to take him back in a few days if he doesn't improve and he hasn't.
Does anyone have any idea what they'll do next??
Thanks

cooksters have just googled in 'problems with front legs in rabbits' - only selected UK sites - and came up with a few that may help. For some reason my computer won't let me copy and paste the link this morning.Sorry and hope Bunny gets well soon.
