Warm weather gives me the burn too, I have ordered slippers from footsmart with freezable gel backs that have slits over top and bottom of foot, not here yet. So, in the last two days I have kept my foot tub full of cold water and epsom salts, kills the burn for awhile. Digging out my sandals and flip-flops, my feet can't see the sun anymore, sheer agony. My foot tub and I are close friends in the coming months, and when my mouth starts to burn I swish with cold salt water, all short fixes but I'm up for anything. None of this is fun but you can do things that get you through the day and even sometimes forget you have PN.......
