Same thing here Glenn and Greggg,

As a matter of fact, I described it to my PM exactly like lifesaver described it...a cell phone vibrating in my left leg. But I KNOW it is coming from my lumbar spine since the left side is the worst. When I receive a block and calm down the nerve root...it stops. Anyway, it was doing it last night and it is hard to sleep. I just think my spine is getting worse anyway so it is time for another MRI. The last one was done two year ago.
