I "accidentally" set myself on fire once. Ended up with borderline 3rd degree burns covering both arms from the elbow down to finger tips. Even after dilaudid,and a morphine drip my entire world was pain. I've had pain that lasted longer, 2 month access in jaw and 40 years of pain from a car accident. But far and away the fire was the worst pain, before I got to the hospital I could feel myself slipping away.
