Here are some things to consider, maybe discuss with your doctor if you’re talking about more surgery or different treatment -
And, I can’t stress enough, I didn’t work in rehab but have enough understanding that focuses the searches I do. I might have good questions, but not answers.

Nerves are so complex, that I may be over simplifying this info. Small fiber PN, causing the tingling, numbness, and some burning, is from sensory nerves located near the surface of the skin. It is not damage to the nerve pathway that carries deep pain and pressure.
There was a study about post-decompressive neuropathy including a case study somewhat similar to you, look near end of article.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6284122/
This study does say that this type of neuropathy can resolve itself, although the case study had steroid injections 3 months apart.

A question that I would want clarified for myself from the doctor - is whether the nerve damage is coming from the area near your stenosis/laminectomy, that is central-to-peripheral, . . . or is there damage to the nerves that is happening near your lower limbs and moving upward, peripheral-to-central. Peripheral-to-central is typical of diabetic neuropathy, Epstein-Barr, ALS.
It would make a difference in the type supports you’re considering, Accelera, and Walkasins,
My guess is that Accelera is intended to help preserve nerve transmission in systemic type nerve issues (diabetes, Epstein-Barr, ALS). It may not help nerve damage that originates in a central area - and possibly could irritate nerves that are trying to repair themselves.
(Notice I say, guess, and possibly a lot - I have questions not answers).
The Walkisins state they send sensation back up the pathway to be interpreted as foot movement. Looks like it sends a signal when there is heel pressure, and when there is toe push-off. Forward movement. But whether the signal that is sent through a band on the lower leg is being sent through the sensory nerve pathway, and possibly more difficult for the brain to interpret? Walking involves deep pressure.
The Walkisins band must also reach up above the area of tingling and numbness - it has to send signals through working nerves, not damaged ones.

I damaged my L5 nerve about 35 years ago. Ortho surgeon said I had pinched the nerve as it ran near the hip joint. I actually jammed that hip/leg while run/walking over rocky boulder field at night trying to keep up with middle schoolers at a church camp.
Resulting damage: I could not push down well with that foot, lost the ability to lift my big toe, and had excruciating pain in the calf of my leg on that side. Pain relievers, anti-inflammatories, and time. By 6 months the pain was gone, with some residual toe lift problems - stumbling on slightly raised surfaces that caught my toe. I don’t notice a problem now except when I’m extremely tired. If I have leg cramps, or foot tingling (not often, and maybe calcium/potassium/dehydration related) but it’s always on that side, or worse on that side.
One thing I did that temporarily relieved the excruciating pain, was to position myself so that there was no pressure on the L5 nerve near the area where the damage was. That meant, I would lay face down across the bed, with my hip just slightly supported on the edge, and my legs hanging toward the floor. If I put much pressure on my feet/legs it sent jolts of pain. I had very little pain when my hip joint was not being compressed - the joint was pulled apart a bit by hanging across the edge. I mention this because you (although you’ve said your pain had diminished) or others reading this post might be interested in trying to find a position, even if it looks weird, to reduce the pressure in the area where the nerve is being compressed.

More on what I take for current PN, next post.
