I’ve had severe spinal stenosis for yrs and the thing you must have is a mattress that’s going to hold your spine up straight while you’re sleeping and a regime of stretching in the morning and at night if you can. I take Tramadol Gabapentin and Tylenol 4 times a day . And you might want to go to pain clinic to try injections for your back they haven’t worked much for me but they do for some. Or you can opt for surgery
Hope that helps good luck
