Have you been to a neurologist yet? And have you had a emg/nerve conduction test done? I think this test would help in determining your issue.
I have peripheral neuropathy and also lower back disc /arthritis issues. As you may be aware, the emg/ncs tests can detect large fiber neuropathy…however it typically can’t detect small fiber neuropathy (this can be detected via a skin punch biopsy). I also am pre-diabetic.
Best of luck.

Hello @lewin. You will notice that I have moved your post into a discussion on lumbar stenosis and neuropathy, which you mentioned. You can find your post here:
- Neuropathy from lumbar stenosis?: https://connect.mayoclinic.org/discussion/neuropathy-from-lumbar-stenosis/

I see that @stallen has joined you and is also pre-diabetic, so I will encourage you to connect.

Have you been seen by a spine neurologist?

I can strongly recommend Dr Mark Knaub at Penn State Spine and Joint Institute, in Hershey. I drive 2 hours to see him.
In 2017, I had a large lumbar disc herniation with severe sciatica and sensory and motor neuropathy in one leg. I did 2 epidurals, 2 courses of PT, little relief. I had very successful spinal surgery at Hershey, but continue to see him yearly due to my now diagnosis of moderate spinal stenosis and degenerative disc disease.
I saw a neurologist in Hershey last summer and had an EMG which showed the neuropathy is not due to “nerve disease”, but is coming from the spine. It is getting slowly worse, now getting symptoms in the other foot, but I do feel better knowing what’s going on.
I need to wear an AFO brace now to stabilize my ankle while walking and am in PT again.
All we can really do is just keep going and find joy in small everyday things (the robins are back up here). It’s great to have this group to share with, we look fine, but neuropathy is a “thorn” that never goes away.
