What can I do to improve mornings?

I've been dealing with this for a year now. Results of my MRI from august below. I herniated last June. I felt like I was getting better by September, and then slowly things just got worse until suddenly in December I couldn't stand up in the mornings without extreme pain. Before december, I would get up and hop in the shower, but since then I have to crawl on my hands and knees when I get up because it hurts too much. After about an hour of sitting in a chair, my discs dehydrate enough and then I can get up and walk. I went through 8 weeks of PT at the beginning of this year and have continued the exercise program on my own since then, and I'm not really seeing any improvement in the mornings. Occasionally I'll get a week where it seems like the morning are getting easier and then it just goes back to awful. I can't figure out a pattern either. I've been doing Stewart McGill's back mechanic book for a couple of months now, but I'm getting the same sort of random results in the morning. A few weeks ago I was actually able to stand up in the morning for about 3 days and now I'm back to where turning to crawl out of bed is awful.

I don't have any leg pain. It's centered right on my spine.

It's driving me insane. I'm fine after that first hour or two. I do most normal day-to-day stuff like mow the lawn, clean the house, etc. I converted to a standing desk in January. I walk. I sleep with a pillow between my legs. I lost 50 lbs. I do all the spine hygiene stuff that McGill says to do. What can I do to make the mornings less awful? I just want to be able to stand up and take a piss in the morning without feeling like someone stabbed me in the back.

Study Result

Impression

1. Degenerative changes in the spine with possible impingement of the left S1 nerve rootlets along the lateral recess at L5-S1.

2. No acute fracture. Edema along the L5-S1 facet joints can be seen with facet inflammation.

FINDINGS:

ALIGNMENT: Minimal grade 1 retrolisthesis of L4 on L5 and L5 on S1. Several Schmorl's node deformities are present. No pars defects identified. Vertebral body height and alignment is otherwise normal.

BONE MARROW: Mild edema along the L4-5 facet joint may represent facet inflammation. Degenerative endplate signal changes are present without evidence of an acute fracture. Mild disc height loss at L4-5 with moderate disc height loss at L5-S1.

CONUS: The conus medullaris is within normal limits, terminating at the T12-L1 level. No definite evidence of arachnoiditis.

DISC LEVELS:

T12-L1: Unremarkable

L1-2: Unremarkable

L2-3: Mild facet disease without disc bulging, spinal canal stenosis, or foraminal narrowing.

L3-4: Minimal disc bulging and mild facet disease without significant spinal canal stenosis or foraminal narrowing.

L4-5: Minimal grade 1 retrolisthesis. Mild diffuse disc bulging with small central disc extrusion with superior migration.. Moderate facet disease with fluid in the facet joints, right greater than left. Mild spinal canal stenosis with mild bilateral lateral recess stenosis. No definite impingement of the L5 nerve rootlets along the lateral recesses. There is mild bilateral foraminal narrowing without definite L4 nerve root impingement identified.

L5-S1: Minimal grade 1 retrolisthesis. Mild to moderate disc bulging and hypertrophic osteophytes, asymmetric to the left. Mild facet disease. Mild spinal canal stenosis with mild to moderate left and mild right lateral recess stenosis. Disc abuts but does not definitely compress the left S1 nerve rootlets along the lateral recess. There is mild to moderate left and mild right foraminal narrowing. No definite L5 nerve root impingement identified.

LUMBOSACRAL JUNCTION: It is assumed for the purpose of this dictation that there are five lumbar type non-rib-bearing vertebral bodies. The lowest lumbar type vertebral body will be designated as L5 SACRUM AND SI JOINTS: Unremarkable OTHER: No acute paraspinal soft tissue abnormality.
