Patient further stated that while it was being administered her cheeks, mouth and lips started quivering and twitching.

Her left cheek area felt swollen and tingly. She stated that it felt swollen but it didn't look swollen, like when you go to the dentist. She also experienced pressure around the eye sockets. She added that both areas under eye sockets felt a little bit weird, tight or something but not like a pain, hard to describe.  All of these symptoms resolved within a few hours, and 24 hours later she's "pretty much back to normal".  The pressure around eye socket, lasted for a few hours; while trembling and quivering only happened when the shot was being administered, and 24 hours later, she was pretty much back to normal. Patient asked if this has this been reported before and if she should she get her second dose. Patient stated if this could this be a sign of Bell's Palsy, and was it likely that she develop Bell's Palsy (30Mar2021). Patient stated that all her family have all received their doses and no one had this kind of reaction. She wanted to take the second vaccine, just doesn't want to have a stroke or heart attack or anything like that. She stated that all of her events are completely gone except she still has a little bit of swollen feeling left in her cheek on a scale of 1-5 with 5 being the worst, she would say it is a 1, its pretty much gone, the swollen feeling. She stated that provider was aware of the events because she called and told her yesterday. Her family got their vaccines either moderna or Pfizer and have had no issues, other than typical ones such as forearm, a little bit of nausea, or fever but nothing like what the caller has experienced.
