1) must have a good bed. Soft at the shoulders firm thru the lumbar legs
2) try sleeping a bit elevated
3) MUST TRY: Radio Frequency Ablatia (RFI/RFA) in your stenosis facet joints. It helps better than anything I've ever tried. Not consequential as far as no steroids or drug interactions. Can be a permanent fix. But might need again. there is pulse and heat. Heat only works for me. first time it lasted 15 years for me.
Massage
4) Acupuncture
5) anything that increases circulation and gets the blood through the stenosised joints smoothly.
Maybe you have some modicum of edema. If so, control that and you will feel MUCH better. We get swelling morning/night with edema and creates problems with stenosis.
My stenosis is pretty well controlled now. The ablation was the best thing for me. covered by Medicare.
