You need to find your trigger.... if you want to improve your PN.

There are many things that cause PN, so you have to be a detective of sorts.

Our subforum above has some posts for informational use.

Also you need to have B12 and Vit D3 serum levels run to see if you are low in these.

The most common causes are impaired glucose tolerance or frank diabetes, RX drugs used, exposure to solvents, pesticides.

Diet can be a cause... food intolerances include gluten (from wheat, barley, and rye), and also nightshade vegetables.
MSG in processed food is also a trigger for increasing pain.

Candida infection of the bowel, can increase aldehydes (by products) in the blood (like alcohol does) and irritate nerves.

There are supplements you can use to help, and they work by healing or correcting metabolic changes in your body. But you have to have an idea of what is wrong with you before choosing the correct ones to use.

Pain in the feet can also come from mechanical problems with the spine, or neck. Also many things can go wrong with the foot, like compression of the nerves (like what happens with low thyroid issues), or gout, or arthritis, or tendonitis.
Sesamoid bone issues and inflammation cluster at the ends of the feet. So getting a full evaluation at a good podiatrist is valuable.
