Tuesday I accidentally poured hot bacon grease down my leg at work. It got caught around the top of my shoe giving me severe 2nd degree burns around my ankle. I have 3 blister, and the largest is about 1.5 inches by .5 inches and is under the Fibula. I can't wear shoes until the blisters pop, making me unable to work. How long after the initial burn should I wait to pop and drain the blister myself? I can provide a picture if needed.
