I think allergic reaction resonated in terms of the swelling. My ENT did 2 CT scans in October. One of the right side of my lower face including jaw and neck. Did not show anything suspicious. He also did a CT scan of my sinuses since I have a history of chronic sinutitis. It show some inflammation of the sinuses, but not a lot. Because of some off and on numbness on that side of my face and mouth that started 2 weeks after my booster (Sept 29), he is referring me to a neurologist.

More background info -I noticed the lump and swelling initially 3 1/2 mos of the first 2 covid vaccines I had in February. These never completely went away before I got the booster. Both my primary and rheumatologist said to get the booster even though I told them what was happening. The very next morning after my booster, my face was swollen more. The right side is still puffy.
