I would be amazed if this were neuropathy as it normally doesn't happen this sudden. I'm with the others, it's probably a pinched nerve which any specialist doctor, osteopath or chiropractor could soon sort out.

The first thing I would try is to undo the pinch - try slowly rising onto the tips of your toes a couple of times keeping your legs together and also straight - its a medium length shot; but it might work, saving you some medical costs.

Good luck and try not to panic.
