I’ve had PN for 16 years. My feet stay cold. I’ve had them checked with a temperature gun. My feet stay 35-40 degrees colder than the rest of my body. They do feel like blocks of ice that are going to burst. The pain is sometimes unbearable. I have two spinal stimulators implanted in my spine. Neither help with my feet. I have tried everything, I’ve heard of. To no avail, I’m falling 2-3 times a week. That’s walking with a walker. I pray that one day God will relieve my pain.
