Laura's gotten good information from nerve studies but it was a three hour long, stick everything all at once, extravaganza before enough could be determined to help her. She had the normal one-area-at-a-time style of nerve testing and gained the only information possible from that kind of testing: it hurts and it's expensive.

Hope, by any chance do you have problems with other joints beyond your spine? Knees possibly? I only ask because knee damage can lead to something called quadricept inhibition that can lead to your leg giving out from under you as the muscle fails to protect a damaged joint. I would say, though, if you aren't sure you have serious knee damage on that leg, I'd treat it as a serious spinal problem rather than take the risk of ignoring the problem.
