Skin treatment for my son

My 1 year old son has Atopic Dermatitis (Eczema) and I would like to raise some funds for his skin treatment. It is very expensive and I am currently unemployed so I can hardly afford it. He has very itchy skin and he is always scratching which ends up in him hurting his body because of the scratching. He doesn't wear diapers anymore because they make it worse and nurses thought it was because he stays for long with wet and soiled diapers but a doctor diagnosed him with dermatitis. He just plays around the house the whole day naked because if he is covered for too long then it gets worse, we hardly go anywhere because he has to be uncovered most of the time, especially when it's hot. There is a free cream he gets from the local clinic but it only works for a few minutes then he starts itching again. It breaks my heart that he is going through all this and I feel helpless, so I am appealing to the world out there for anyone to give the little that they have to help me help my son to be well.
