Yes, I have asked. It is not lupus. That was the first thing they thought about. Explanations are vague. I was told that whatever it is it is "mild," whatever that means. The original rheumatologist I saw is no longer at Loma Linda. I see my primary later this month. I have other issues that I am going to push him on. With no symptoms I would probably ignore it but not with Covid raging around the world.
