I also suffer from PN and I am not a diabetic. When I was getting my chemotherapy treatments, my feet started to feel like I was walking on rocks. I thought it was my shoes but, it was not. I did not have pain only incredible numbness which created problems with my balance so I fell several times.

I would like to say that everyone reacts different to remedies suggested for PN. My journey for improvement has been as follows:

I checked in YouTube and found
Exercises for Peripheral Neuropathy in the Feet and Legs
The instructor is a Kelly, a physical therapist, that specializes in exercises for oncology patients. These exercises helped me a great deal with my poor balance that was contributing to several falls but, I still had the numbness.

The next thing I did was to sign up for Electroacupuncture that is Acupuncture that uses electricity to enhance the benefits of the acupuncture treatments for pain management and stress relief.

After 5 treatments I was able to spread out my toes that previously had felt like they were glued together. When I finished the 5 treatments, I decided to wait for follow up appointments because these treatments are not covered by my insurance.

I then purchased a Collapsible Foot Spa, Foot Bath Massager with Heat, Remote, Timer, and 24 Motorized Shiatsu Massage Balls, Foot Soaking Tub Supports Hot/Cold Water Soaking- BA03H in Amazon.

Every day, I fill the Foot Spa with water and add 1/2 cup of Epsom Salt, set the temperature and massage selection comfortable for me and use it for 20 minutes. Once I turn it off, I keep my feet in the warm water until it cools down enough to empty the container. This has been very helpful and I don't think I will go back for additional acupuncture.

I finish my day by wearing socks to bed at night and feel much better. Hope some of this may be helpful for you.
