That stretch may help also or any of the many variations of it. So, if you go to the chiropractor...they are essentially position you into what it would be to do that stretch on their table. But they are going to use leverage and just twist you so far that it will pop that lower disc in alignment. It is kind of like a training wheels type of thing. The chiro will pop you in place and your body feels what proper alignment is like. But then you will go to old habits and have to get readjusted. It's somewhat gradual...not an instant fix.
I wouldn't be surprised if you had stenosis if you also had some foot issues. Because once the stenosis is fixed then the chiro will probably need to start looking at your hips. Lay on the ground and raise each leg and see if one can raise easier than the other just out of curiosity.
