Ok guys here is my history of having had to deal with eczema on my shoulders,back and thighs. I hope this isn't a too long read, and I hope that I can get some help from knowledgeable people here 

2011: I think it all started about March of 2011 when my skin started to feel itchy every time after taking a bath.I was using Dettol antibacterial soap to wash my body at that time. And then a few months later, suddenly I notice my skin at my shoulders and back has been getting some red spots. Thinking it was just normal rashes, went to get some Calamine lotion and applied. Found out that it didn't get better, went to see skin doctor(Dr.Ranjit in SS15), and he told me it was eczema. Gave me some creams, and told me to apply every morning and night. The red spots went off like a miracle, but then I stopped putting the cream because I found out through  Google that creams for eczama are steroid creams, which is not good. So eventually the eczema all came back.

2012: Didn't do anything about my eczema in this year, other than just using Cetaphil Gentle Cleansing Bar( it's a bar soap) to wash my body. Thinking that it would get better, but it didn't. Every time after bathing, my skin would be dry and it would be damn itchy, wtf some more it's Cetaphil, supposedly good for eczema skin. Bought Cetaphil moisturizer as well, not the kind u see in pharmacies now, but the moisturizer I bought is the one with white tube and pink labels. Maybe it's a discontinued product because I have never seen it in pharmacies already.Applied moisturizer for a month. Moisturizer didn't do sh*t either, so got lazy and stopped using. But continued using the Cetaphil Gentle Cleansing Bar till now 

2013: Still the same, but these past one week a few pimples with pus has been coming up around my back and shoulders and my  eczema looks like it has gotten more red now. My eczema might not be too serious if u were to view my skin I guess, and my lifestyle is not affected such as having to eat this medicine and that medicine or having to avoid water and all that, no I don't have to do all that. But the dryness, itchiness and redness especially after bathing is damn annoying, and if I ever take off my shirt when I'm out in public or at the beach, I guess ppl would be running away from me when they see my shoulders and back having all the spots and redness it looks like as though I got skin disease!

So I need some help please? How do we cure eczema? Is there no cure for it?

Steroid creams not recommended to be used too much because it can thin the skin.

You get eczema because of asthma? How does that happen? And what cream are u using now?
