It sounds like you have eczema, and since the two creams you were prescribed are eczema creams, that must be what your doctors though too. This problem can't be cured. It can, however, be suppressed and made to go away--but only if you don't pick and scratch. If you keep doing that, no cream will help. When you say "did not help," I suspect that you mean, "it made it better but then came right back." If so, that is called "helping" when it comes to eczema--it's the best any cream can do. Bottom line: use either cream twice a day, moisturize with any lotion you wish as often as you wish, and don't scratch. If that doesn't help, please see another skin doctor for further advice.
Take care.
