I have it.But I got treatment while in China at a Traditional Chinese Medicine hospital.
Treatment was heavy massage,then acupuncture,and they have a herbal medicine to treat spinal stenosis.Took it for 5 days and no more pain walking or leg numbness.
2 acupuncture treatments and no more pain.
Acu4U in Houston has a Traditional herb pharmacy.Dr.Ben there has similar herbal medicine in his pharmacy.
