Unbearable Neuropathy

The peripheral neuropathy which is largely on bottom of foot is extremely hard to walk on with the inflamed pain. Pregabalin doesn't help, nor lidocaine patches. And since I'm walking abnormally, foot is ruined even further.
I find myself unable to do simple tasks with the chronic pain of PN. I suggested to my pain specialist seeing a neurologist, but he informed me we have to get the pain under control first. That hasn't HAPPENED. At a loss what to do.
