Good diagnosis, Jeff: these do indeed sound like eczema. The little bubbles you describe are no doubt blisters. You can't see them in a patch of scaly eczema--you'd need to look under a microscope, but where the skin is thick, you can see them. Anyhow, it's mot catchy, so you can ignore it if you want. If they bother you, a precription-strength steroid cream may help.
The condition comes and goes, more or less at random.
Best.
