Reporter reported as, she has been experiencing swelling of her soft tissue palate at the back of her throat which started 3 weeks ago. She said that she feels like she can't swallow, it comes and goes and has been in the ER multiple times because of this. The roof of mouth also feels dry and sticky and achy. She has muscle pain at the left back side of her mouth. She enquired regarding reports on this and as to how long she will be experiencing this. She was taking Pfizer COVID vaccine as she got very paranoid, they instilled a lot of fear, she has a lot of autoimmune diseases too. She is just wondering if Pfizer has had any other people with similar symptoms to what she had after the second vaccine in March. She just started getting some insane symptoms in her mouth. she's been to the hospital 3 times with swelling where her soft tissue palate gets swollen and the nerves start getting crazy. She wasn't sure in the beginning if it could be tied to the vaccine, but from her last three hospital visits they are kind of questioning it, its kind of an unexplained reaction. It started where she felt like she couldn't swallow so they ran tests, they thought maybe it was strep throat and everything got cleared. It was nothing viral, nothing medically they could find. They could see the swelling, but theres no reason for it. The back of her tongue feels like it swells feels like she's gagging. It swells then it goes down. It gets worse then it's go back down. It's not getting better, but progressively gets worse then stabilizes then worse again. It just won't go away. She was a little skeptical of the Covid shot as she had flu shot which she did get Guillain-Barre. She was told it was safe. She was tested for strep probably 5 days after her symptoms started. She also got a Covid swab too because they didn't know what it was. They tested her for everything, viral, bacterial, Covid, strep, and everything came back negative. They are kind of puzzled, she's having symptoms, they come and go and it drives her to the emergency room because of the swelling in the soft tissue in her throat. She did read online there is some people with the vaccine have had swelling so she thought and wondered if its related.she went to the emergency room three times and she has been to an ENT, neurology, her family doctor, she has been everywhere. They discharged her every time she went to the hospital. they see the inflammation almost like it's spasming, as it gets spasms and goes down then goes up, it's very spontaneous. She went to a gastroenterologist and they did a scope and they said it was red and inflamed all the way from the back of her throat to her soft palate and all the way to her stomach, it's swollen and inflamed. She states that's why she's on steriods. They thought it could be a viral infection and the biopsy came back and it's not so they are questioning the vaccine. She states Rheumatology, they also did a test to see if her inflammation marks are high and they weren't so it shows it's not her autoimmune, it's something else. The patient underwent lab tests and procedures which included bacterial test: negative on an unspecified date, endoscopy: red and inflammed all the way from back to throat on an unspecified date , sars-cov-2 test: negative on an unspecified date on May2021, streptococcus test: negative on an unspecified date on May2021, viral test: negative on an unspecified date.
