Born With Severe Atopic Dermatitis, Severe Sinus And Breathing Problems, Stings Horribly. Permanent Cure ?

I was born with severe atopic dermatitus,. I spent 5 years in a classroom,teaching,that leaked so badly it was like a waterfall on one wall. It was never fixed and grew worse each year. 3 years ago the air condictioning in my class was turned off during and extremely hot fall. ( August to November) the temperature stayed betweenj 78 and 84 degrees. I kept bags of ice for the kids and use 4 fans. I had alot of sinus and breathing problems during this time. I am also asthmatic and allergic. I developed a terrible red rash on my scalp ,neck and chest. I was out alot due to the pain I was in. Last year 2012 I was in the hospital for over a week because of my lungs. I since have continued to have this rash in the same places. It is not like the eczema, it is hot,stinging horribly. I can not find a derm who seems to have a clue. I have been on oral cortisone off and on for 3 years. It will not it back enough that I can rest for a week or so and then it comes back.
