Drop Foot, Neuropathy in Right Leg from Knee Down No Trauma

My name is Melissa, I am 25 years old August 2011 I woke up with drop foot and a numb right leg from the knee down and dizzy spells to the point of almost blacking out. I've always been healthy no diabetes, always athletic etc. The only thing I contracted prior to this was 3 weeks prior to symptoms I had strep. It is now the end of October I have seen orthopedic surgeons and neurologists I have had steroids, cat scans, xrays, mris of my back and brain, blood tests, emgs and I still have no answers. My DR. is sending me back for more blood testing to look at thyroid conditions and diabetes again (although I've never had high sugar in my life and it doesn't run in my family) I feel like im getting the run around and its very frustration. I know where you're coming from though. We at this point have ruled out any trauma, any back issues and MS. What about you? Any suggestions for me? I want my life back, I have a toddler and a husband in the Marine Corps...What the heck is causing this?!
