You have had a lot of good suggestions. Nanci threw out oatmeal baths. I cannot survive heat rash or exzcema flare ups without them. You can get a box of Aveno Oatmeal bath packets at the drug store. It really soothes irritated skin. Just be careful, it makes the tub slick. They also have a lotion that I use and love it! Plus it is fragrance free, so it doesn't cause additional problems.

I try to stay away from steroid/cortizone creams until my skin is at the worst point. I think you can build up a tolerance to these and they lose their power. There may be other reasons to only use them for a short period of time.
