If the gabapentin helps, have you looked at pregabalin? My doc suggested it and it’s like a super gabapentin. Much more effective, less side effects.
It’s been a huge help for me… Made the difference between active and not active most days.
Steroid epidurals also helped me a lot, but your needs might vary.
If you are decent with script type stuff, and have tasker, I believe you can build your own via kwgt:

You can use tasker to set up variables that kwgt then can render in several ways.
I’ve only done simpler things but it’s worked well for me for years.
