Welcome to the forum. I too, wish I had more information to give you on this. I've never experienced anything like you've described. The only way to really know if it's lupus attacking your stomach is to have a biopsy of the tissue taken. That way they can see if there's inflammation going on, and other things. I'm not sure what other test they could do. Maybe a scope with a camera on it? I hope someone will come along and shed some light on this for you.
