It’s called Zostrix
It’s called Zostrix -HP or formerly Axsain. Yes it does help the burnng fire feet! It’s a Topical Analgesic Cream and takes some of that nasty burning away. Does not take away pain though! But does help some. You apply 3 to 4 times a day. Great for diabetic neuropathy. My father introduced me to it years ago and I forgot I still had some left. Just placed some on my feet and it did help it out a bit!
