At first it came from a bad back, I had neuropathy just a little in one foot and up into my lower leg, to where I couldn't feel those pins they stick in
me. It was in
the sole of my foot on the side
, had the same swelling as you, stingy, and redness, pain. Well, then I had chemotherapy, and that can induce neuropathy in the hands and feet, and after a year it subsided in my hands mostly, but my feet are still a pretty big problem, which now they will be that way for good.
