My derm can't tell if I have atypical scabies or atopical dermatitis. I get relief but not cure from oral ivermectin and oral immuran, please help?

However, if you live in a dorm, share bed with some one, and they happen to have similar itching problem, you might have scabies. Itching from scabies may linger for months after "cure". Atopic dermatitis comes and goes. ...Read more

People with allergic problems, regardless of the type, asthma, hay fever, food allergy, all these are associated with eczema. The best treatment is to find out what you are allergic too. For now try Claritin (loratadine) and see doc. ...Read more
