I am right where you are. I had Vertiflex installed at l2/l3 for severe stenosis with "shopping cart syndrome". Did not help "shopping cart syndrome" at all. Now I am looking in to MILD. My concern is the procedure could worsen my severe stenosis because I have very little space (5.2 mm) for spinal nerves to pass. Seeking folks who may have had the procedure with similar conditions than me that was successful.
