i went to my highschool's graduation last sunday, and got intensely burned on my left shoulder/some of my right.
well it hurt very badly for most of this week, and looked swollen. I couldnt raise my arm because it would hurt too much where the skin folded over.
So i went to see my school nurse and she said "LAWL I CAN'T GIVE U NUFFIN. SOMEONE HAD AN ALLERGIC REACTION TO THIS SUNBURN STUFF... so..ttyl~"
and my mom bought some aloe+lidocaine stuff which was nice for 5 minutes but didnt make it hurt any less.
SO I RUBBED LOTION ON IT! and it felt better (continued this for about 3 days)

but now, it is still very red, but there are some snot-coloured scabbies where it hurts the most, and it looks like some of my SKIN is peeling off. (not dead skin)

 halp me?

see a doctor ASAP. Your skin is the first line of defence agains pretty much everything.  People who get burnt in fires rarely die from the burns but rather the infections they get from having such badly damaged skin and no barriers against germs. 

as im sure you know there are three types of burns, 1st degree 2nd degree and 3rd degree. it sounds like you have a second or almost third degree burn, and probably a small reaction to the lotion you used, go to a doctor and maybe get somehting medicated.

my skin is extremely fair, i have been dealing with similar things since as long as i can remember. 

I've had a sunburn to the point where it had boils about 3" wide before on my legs. You have to see a doctor and I think they'll give you some type of lotion that has "silver" in it.. or something like that. It helps to make it heal faster and not get infected. But yea, you should see doctor if you have a burn that severe.
