My PN symptoms were preceded by peripheral edema in my feet by about a year. At first I wondered if the edema was the cause, as there is mention of that on the Wiki page for PE, but neuros discounted that—said edema was not severe enough to cause PN.

Whenever my feet are "fat", everything hurts more. Keeping them down (for me) is a matter of diet & exercise (walking). It hurts while I'm walking—short term they swell up & feel "tenderized", but shrink down the next day. YMMV.
