Please help! My skin is horrible?

So I have really really bad alergys! (sorry if I spelt alergys wrong) I'm alergic to corn, nuts, animals, dairy products, grass, ect. So it's almost impossible for me to not do anything I'm not suppoused to. I haves dog but I can't get rid of her! I love her to much. Anyway, my alergys cause me to severaly itch/scratch myself mostly while I'm sleeping. I try wearing socks over my hands but I just pull them off while I'm sleeping and I can't stop! I have really bad inflamed hives and cuts all over my hands and arms and legs. I'm afriad I'm going to get an infection or something. What are some natrual ways to help?
