Suggest Medication For Eczema And Boils On The Skin

My 2 year old son has severe acute eczema. We have tried nearly every lotion and creme available and none seem to work for more than a month. We sometimes have to use steroid cremes but we prefer not too. We have tried to switch around each month and never get results. We have been to multiple specialists and nobody is able to help him. Now he is developing boils that are extremely painful for him. It is painful to watch as he is supposed to be playing and developing but instead he sits down and itches, we are getting desperate and the doctor bills are not helping our situation! What if anything can we do?
