I think you should try Biofreeze gel... it stops much of the burning type pain very well.
Several online places sell it at lower prices than you can find locally. But some pharmacies have it with another name= Perform gel.
Topical things can work for some people with PN... but you have to try them. Some people even use Vics Vaporub cream, and claim some blocking of pain. It is the menthol in them that blocks the other pain sensations.
