I believe, after pounding the keyboard for a few weeks (I used to pound the books; now I pound the keyboard - things change.) that my peripheral neuropathy was caused by peripheral edema in both feet.

My PCP missed it. The first neurologist missed it. I found it on my own.

Interestingly, of all the searches I did on peripheral neuropathy causes, peripheral edema never came up. Then by sheer accident - I don't even recall why - I searched peripheral edema. One of the first links was Wiki, and there - low & behold - was the answer:

Severe swelling can cause permanent damage to nerves, resulting in peripheral neuropathy.

There's a lot more to the story, but I'm trying to be brief in answering the question. Coulda been worse.
