Hello! Welcome to the club! I've had eczema for my entire life. I've gone through stages of what works and what doesn't. I've been through many steroids and found that they, ironically, don't work well for me. (It doesn't make any sense, but what does with me?) When I was a kid, Eucerin worked well (especially the thick one that comes in a tub). Nowadays, the ONLY thing that helps me is this cream that Neosporin makes (it doesn't contain antibiotics) called Eczema Essentials. It has oatmeal in it, like Aveeno. There probably isn't any difference between Aveeno and this cream, but why mess with something that works?
I actually have a wicked case of it on my hands now from a combination of cleaning chickens and a soap I'm allergic to. It ITCHES! And burns. And PLEASE, for the love of all that is good, don't scratch it!
Most creams, especially steroids, work better if you wrap Saran Wrap around them overnight. It sounds crazy, but it works well.
Lastly, if you have it on your hands, my allergist recommended something that usually works for people. (Actually, it works on everyone except me.) You put vaseline on your hands, then put a pair of damp cotton gloves on top of that, and then a dry pair on top of that, and you sleep like that.
Good luck! The trick is that once you find something that works (especially if it isn't a steroid), stick with it!
