@sueinmn; @poppy1946- Good morning. I researched a bit further because I have had swollen lips from a spider bite and it was painful. It does seem that on rare occasions this can happen as a result of the COVID vaccines. It has happened with Moderna mostly and with people who have had fillers. But it can happen with Pfizer too. This is the article that I found:

And as Sue said, stay tuned for updates. Did your doctor give you prednisone?
