Does eczema always itch?

Does eczema always itch? Does anyone have red spots or patches that do not itch. I do have a derm appointment coming up, but wanted to see if anyone has anything similar.
I have these small red dots/blemishes under my skin that do not itch. If I get real hot I may notice/feel them, but usually it’s just that I see them. They are in both elbow creases, pretty much where my elbow skin meets. In other words if I close my elbow you can’t really see them. They are sometimes more visible than at other times, but if I look closely they are pretty much always there. I have a lot skim blemishes on the underside of my arms, but these are different. I have lots of moles, skin tags, and other benign skin issues, but these seem kind of new (but maybe I am just now noticing them). I have generally sensitive skin, and I do get hand eczema in the winter.
Just wondering if anyone has experienced anything similar.
