I can do heat, but Ice feels like someone poured acid on my leg. Luckly Lidoderm works locally for me. I have most of the tearing sensation from the hair follicles, so I shave my outer thigh and move the lidoderm patch around as needed. It does two things, I don't jump out of my skin when my pants touch my leg, and it does block the touch sensation that is converted into tearing burning scabbed flesh from my body.

My rule of thumb for the past 10 years is 1 hour on my feet = 1 day of recovery. Now with the lidoderm I get a free hour after the second hour I need 1 day of recovery, and then x-1 hours on feet = y days recovery now :)
