I slid on gr and got a friction burn I think, how do I treat it?

I slid on gr and it seems like it ripped the skin off, its very tender, water or anything put on it makes it burn, We tried everything. First aid spray, peroxide, soap, iodine, aloe vera...etc. But its still burning, Weve been keeping it covered, and like the cut leaks. Its sweat or something i dont know but throughtout the night, I had a big bandaid on it and felt like water running down my leg the whole night, the bandaid was saturated and so was my sock.
