Eczema Treatment Care

How do you know when eczema is going?

What season seems to produce the least amount of breakouts on your skin? Also, I’ve noticed that whenever I get in chlorinated water my eczema seems to almost disappear, has anyone else ever experienced this?
What treatments have you used, and what have you seen to be the best treatment/medicine for this skin rash?
Also, what causes eczema?

I have really bad eczema and I don’t have insurance or anything for that matter…lotion usually keeps it under control but in the winter it gets worse. I would like to find a cheap, very very moisturizing lotion for my skin. Or even something I can take or eat to help the matter.

I get itchy, bumpy rashes that come and go every once in a while. It always appears in random places on my body. I changed all of my sheets and put some freshly-washed clothes on. Besides my cat, there isn’t anything that could possibly trigger an allergic reaction. (Though I was never allergic to cats!) We don’t even have furniture in the living room yet. My mom dusts, cleans, and vaccums the house every morning and night. We are generally cautious about dust mites and pet dander because we have a sick baby. Is there anything I’m missing that could trigger this reaction?
Also, I just recently had a blood transfusion. If what I have is not contact dermatitis then could it be a reaction to the white/red blood cells that were donated to me?
