i personally feel like that would be a hard job to do. you have to know exactly what to treat and symptoms in each person is different. but i am greatful for the people who do this. i have been struggling with eczema almost my whole life, and regular doctors had diagnosed me wrong so many times. i had to finally get a referral to a dermatologist and they helped me tremendously. i am going to finish reading this, i am glad to see it posted. it interests me a lot.
