Help Me Please!!!! It stings really bad!?

i got a really bad sunburn 5 days ago, and my shoulder started pealing. it is the only part of my body that got sunburned and is pealing. anyways, i grabbed the skin and continued to peal the skin off, i had a huge area where the old skin was gone, and the new skin was on top. a couple minuets later, it stung really bad. i took a shower and put cool water on it. the new skin was really dry, so i put some of that aloe vera gel on it. now it stings really bad!!!!!!!!!!! what can i do to help it and make the pain go away?
