Definitally call the doctor, or better yet make an appointment. Eczema creams contain steroids, and you should never use them on children unless specifically told so by the doctor, and if they do say it's ok, the amount that you use is crucial. My kids (2yrs and 4yrs) both have severe eczema with cysting, and we used eczema cream for only 4 days, and the dermatologist said that is enough time for the medicine, and as preventitive maintenance we use Eucerin every night before bed with the skin wet. Sounds more like maybe a reaction or something. But steroids are nothing to screw around with, so I would say go to the doc. And not just the regular pediatrician, an actual dermatologist. It's better to err on the side of safety than trying to self medicate. Hope this helps! Take care.
