Severe nerve pain

I know this has been discussed on here but this year I started experiencing severe nerve pain. Feels like a combination of aches, pins and needles, sharp pain mainly in my toes and feet. I also get involuntary movement when resting, especially in my fingers and legs. Just this week I’ve noticed that when I’m walking my legs feel shaky and weak, like my legs are going to give out.
My arms and fingers have moments of weakness and aches along with the involuntary movements.
My neurologist put me on gabapentin but I had blurry vision, I’m already suffering from sinusitis, head and ear pressure that causes my balance to be unstable, so just could not tolerate the blurry vision on top of all that. Then we tried Lyrica, wasn’t any better as far as side effects, was very lethargic, blurry vision wasn’t as bad, but still there.
Would love to know if anyone else has experience these symptoms, and did you find relief from any treatment for it?
I would greatly appreciate any feedback.
