Might be time to see your doctor if the pain meds aren’t doing making the pain any more tolerable. I have herniated a disc in my lower back, I have stenosis in my lower back and have had sciatica on the left side of my back (not all at the same time!) I have been evaluated by a doctor…the X-rays, and MRI’s confirmed it. It took some time and PT to get through it, but I did. Occasionally, the stenosis can still be a problem, but not near like it used to be before I started riding my bike.
