How can one prove their skin and surrounding tissue is hardening?

“place thee lotion on thee skin”

those are calluses on your feet, I have taken Eucrin Creme and put it on very heavily and then slept with socks on it will soften your skin on your feet. See the link for addional info.

No, the question is how do I prove something extremely bizarre and extremely painful has happened to my feet. No lotion or other medicine will comfort it. Severe pain.

Talk to a doctor. The condition isn’t unknown, and it is acknowledged to be painful and serious. See a doctor.

It sounds like scleroderma (from WebMD.com).

Then call a podiatrist they are the doctors for feet and can help you, if it has to do with the foot they are the people to see

Is the skin on your feet actually hard, or does it just seem that way due to the pain? If it’s the former, I’d be concerned about scleroderma, as @WasCy says. If it’s just the way the pain feels, it could be neuropathy. Either way, a doctor’s appointment is the way to go.

@augustlan Yes, it is hard and feels rock hard.

To the doctor, then. Keep us posted!
