How's Riley this morning? Hope feeling better? If it helps, Nikka had something very similiar to what you describe. Her nose was huge and one eye was swollen completely shut. The vet thought she was stung by something. Benadryl didn't do anything so they gave her a couple of shots, but it still took a few days for the swelling to start going down and over a week for her face to get back to normal.
Wishing you the best. Keep us posted
