As I've mentioned in other posts, I use this and it works for the burning. It is very expensive & it isn't covered by my drug plan so I use it only when I am in serious pain. It also works for 3 to 4 hours...longer than Biofreeze.

I also use Biofreeze which works well and has a very soothing/cooling effect. It is also more cost effective than prudoxin. I buy it @ Amazon where it's less expensive than @ my local drugstore.
