PNers mostly have burning symptoms, or numbness.

So the Biofreeze is good for that. My major symptom is burning too. Biofreeze has menthol in it which activates the cold sensing nerves, which overrides the burning signals.

I find capsaicin horrible...many of us (PNers) cannot tolerate it.
It was hard to find in the ingredient list of Healthifeet because it is abbreviated.

I believe the website has a free trial sample. I think that would be the way to go with it.

Arginine can be used orally, and there are magnesium creams available too.

Arginine is included in erectile OTC products for men, because it dilates blood vessels. It might help with RSD vasoconstriction, but that would be an "experiment" you'd have to be willing to try it orally. It is also available in a powder called ArginAid. I've seen it used for patients in long term care who have resistant healing of bed sores, etc.

Taking too much arginine orally however, may set off shingles.
Arginine is a viral stimulant, for replication. L-lysine is the balancing amino acid for that complication.

So I like the idea of a cream. I'll keep looking for one without that pepper extract.
