In my experience, burns are the worst. I once got a powder burn after playing with firecrackers when one went off in my hand. The thing about a powder burn is that the powder embeds itself in the skin, which intensifies the burning sensation. I also got a bad burn on my wrist when I was drunk and making gravy. It completely sobered me up and I could feel it shooting out to the ends of my nerves throughout my body. It only stopped feeling like it was on fire several days after the fact and growing the skin back on that shit was a bitch. I have also eaten shit on a bike and road rash is pretty awful as well. I remember I had to soak the bandages on my shoulder to get them off without tearing the scabs/new skin. Hope you'll be ok.
No real story. Was drunk, fucked up, now I have a scar. Oh! The burn, when bandaged made my co-workers briefly wonder if I had tried to kill myself, which I had not. They were relieved until I showed them the giant blister. Then, most of them wanted to throw up.
Officially now, nothing has ever compared to the pain I was just in to take the x rays. I can't move it more than 15 degrees in one direction already without pain. I just had to turn my arm over, already phenomenally painful, and then turn it all the way out and hold it over the table. I've never had "everything absolutely leave your mind" pain like that. I would ever forget that feeling now.
On the subject of road rash, I still say one of the weirdest experiences in my life was when I was probably 10-12 somewhere in there. I was riding my bike one day, and I don't know what happened but the next thing I know I'm standing on the road, a bit to the side of my bike and my bike is just crashing forward. Like the bike was sliding on it's side against the road. I don't remember anything else, just one second I was on my bike, the next I wasn't and it was on the ground. I originally thought I jumped off, but the fact I was standing straight up and staring straight at it makes me question.
Must have been, I'm sure I jumped off somehow, but it's crazy to me that I could do something like that and not even have thought about it
When I was 9 or so, I microwaved a marshmallow and picked it up. Homemade napalm. It wouldn't come off, and it kept burning. That was when I learned about the different degrees of burns. That said, if you haven't microwaved a marshmallow, I suggest trying it. Nuke it long enough to swell up, but not so long that it burns. Then put it in the refrigerator for 10 minutes or so. It's delicious.
