Neuropathy? Does a foot massager help? I got a wooden one on Amazon for like $20. Love it.
Foot pain can also come from issues in the lumbar area (low back). Terms to Google are L4 or L5 misalignment, sciatica, lumbar stenosis.
Also check into cervical stenosis. Stenosis basically just means things are narrowing in your spine and pressing on your nerves. This can cause many of the issues you've listed earlier and below. If you do the wrong stretches, it can make things worse.
