Don't know about cheap, but you can get over-the-counter corticosteroids that should be enough to clear up very mild eczema. If it doesn't respond to that, head over to your doctor and get a script for a stronger topical corticosteroid. And if that doesn't work, get a script for a low-dose oral steroid.
(Why yes, I am a lifelong eczema sufferer, why do you ask?)
As for what you're allergic to, you can get a test from a dermatologist that will test you for allergies to the most common allergens, or you can get a skin biopsy and see if they can find anything that way. I did both of those things, which is how I found out what I was allergic to. I don't know about the health care system in the US, so I don't know how much this will cost you, but your insurance might cover it, I guess...
