If your damage is at the dorsal root level, I don't think topicals can work for you. If your pain is compressive in origin, then yes, I think the lidocaine may work, depending on where you apply it.
When I had my carpal tunnel emergency during my pregnancy.... not just my palms hurt, but my whole hands were on FIRE... it was truly awful.

This link has diagrams of the nerves in the hand. There are several diagrams. Notice that the nerve comes under the wrist ligament, and divides in the palm. If you had a sensory PN only there the fingers should hurt too, not just the palm.
Have you tried ice on your wrists? Compressions often respond to ice, by shrinking the tissue a bit and taking the pressure off.
