Sure. I mix gel dmso and furazone 1:1. Slather on the leg. I use… maybe like 1/2 c total on one leg? You want plenty on there, but it’s not like a 1/2" thick coat like you would do with a poultice.
Cover with saran wrap.
Wrap with a standing wrap.
I usually do 12 hours sweat, cold hose, 12 hours dry wrap, 12 hours sweat. If things are really terrible, I’ll do back to back sweats, but keep an eye on the skin. I move to a break with a dry wrap as soon as possible.
DMSO + water = exothermic reaction. Only apply to a DRY leg. If you need to cold hose before sweating, make sure the leg is dry.
WEAR GLOVES.
You can also use pre mixed sweats that don’t have DMSO. I like Su-Per Sweat: https://www.su-perstore.com/m7/slesweatointment--su-per-sweat-ointment.html
