i've been experiencing numbness in my right thigh for the past 3 years.  Once a year this happens.  I get up and i fall as if i have no leg at all.  the feeling lasts for maybe 30 seconds.  The past 3 weeks the feeling has returned in my thigh.  I've fallen 3 times, my entire leg feels like an I.V. is in it...very cool.  Not only is this going on, but its accompanied by tingling in my left leg, muscle spasms and tingling in both my hands and arms.  These symptoms lasts for hours.  I'm not over weight, i'm not diabetic and i don't have thyroid problems.  All have been checked.  I went for an MRI/MRA today along with some other blood tests like B12, so i'm just waiting.

Anyone have these symptoms?
