Hi again, Christina. 
I’m not sure if your eye thing is the same as mine. I know you said your antibodies are in check so it’s not GED, but mine don’t swell. They seem sunken and I have darkness in the concave area.
Or.. perhaps the tissue of my face is slightly swollen which makes the under-eye area LOOK sunken?
Accck…… if I’m a person who loves a challenge, I’ve certainly got one with this disease!
