Eczema Treatment Care

I got this eczema from work (thank goodness I’m quitting!) and it’s really annoying the crap out of me. I already got this cut that keeps opening up everytime I move my hand. I started using this anti-itch cream just last night. Hope it works, but if it doesn’t, what else can I use?

I get these tiny red spots from time to time without rhyme or reason? If its contact dermatitis which the dr thought it might be then why do they come at strange times, like vacuuming, walking, after a shower, sitting outside one time I put on some black jeans started iching and sure enough i had tons of tiny little red spots.
there is no correlation to these events or anything I have been in contact with at all those times?They go away after I spray them with cortisone or benadryl
what could i be allergic to, or could dry skin cause it????????
