Eczema looks scaly, not pimply. These could be bites, or perhaps they are part of a viral rash, in which case you might get a few similar pimples elsewhere on your body before they fade out and go away. I would suggest you leave them alone (although Sarna is fine for itch, to keep you from scratching.) If they persist, you can ask a skin doctor to take a look, perhaps the one who prescribed Ultravate.
Best.
