Not the kind of news one wants to hear?
But at least it's sounding as if your docs are trying to zero in on causes and issues fairly clearly.

Who says neuropathy doesn't/can't become serious? It can, and in your case it appears to be. I for one, have acquired a very healthy respect for MY OWN NEUROPATHY!

Let's all hope and pray that it really isn't as bad as it seems? Patience is the art of hoping....
