I use ice packs wrapped in a hand towel everywhere that burns, if on feet not too long-probably about 20-25 minutes... I know you are not supposed to leave them on very long, but sometimes it feels too good to stop using them when it numbs areas that hurt so much...

I think what feels good sometimes is to soak feet in alternate very warm, then very cool soaks under the faucet in the tub...
