A 48-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, Lot number was not reported), dose 1 via an unspecified route of administration (reported left side) on an unspecified date as single dose for COVID-19 immunization. Medical history included felt a little hot prior to the COVID vaccine from an unknown date, neck pain, extreme GERD, extreme racing heartbeat, right eye proptosis, and immune issues from an unknown date. Concomitant medication(s) included oxymetazoline hydrochloride (CLARITIN ALLERGIC); levothyroxine sodium (SYNTHROID); liothyronine sodium; hydroxychloroquine sulfate (PLAQUENIL S); and famotidine (PEPCID), all taken for an unspecified indication, start and stop date were not reported. The patient previously took diphenhydramine hydrochloride (BENADRYL) and had a side effect. On an unspecified date, the patient reported having these feelings in both arms, more so a tingly feeling in the right side of the face, and hypersensitivity in the face. She had a pain that goes from the right side of the face to the back of the brain. Her blood pressure went up. She also had a lot of liquid, and felt dehydrated almost felt like her right side was going to drool. She wanted to know if this could be palsy or a nerve condition. She stated she's concerned about getting second dose because she was still having these feelings. The patient wanted to know if it would be safe to use the EpiPen her Doctor prescribed to her, since her blood pressure went up high, instead of going down, like it usually would happen in the severe cases of allergic reactions; for that and the tingly face, the doctor recommended that she receive the second dose in the hospital. She stated she received her first dose at a convention center and wanted to know if Pfizer could provide her with a letter saying she would need to receive her second dose in a hospital. She was supposed to get the second vaccine on Thursday (unspecified date). She was concerned because of a reaction she immediately had and has had since that timeframe. She felt a little hot prior to the COVID Vaccine. After she got the COVID Vaccine, she felt hot. She was sitting there waiting and felt a little hot on her forehead. She thought she had a little sweat. She also thought she was being crazy because she was hot before she got to the COVID vaccine location. Twenty-nine minutes in she started feeling extreme heat on her face. She was burning and tingling. She felt she was having a lot of congestion. She saw her face turned very red. She had to use a lot of ice because it felt like she was on fire. She was there for two hours being monitored. Her blood pressure was 153/92 when it normally was 100/70. Her blood pressure was checked three times and the lowest was 142/90. She stated she is not allergic to Benadryl, but when she was a little kid she had a side effect so she doesn't use Benadryl. She was given Pepcid immediately after COVID Vaccine. She had red flushness on her chest. She had a tingling feeling under her throat. Her face swelled up a little bit, but enough where she could feel it. She stated she had neck pain prior to the COVID vaccine. Fifteen minutes after the COVID vaccine, she felt pain rise from the right side of her neck to her head. She also felt numbness across her face. It didn't go away. After two and a half hours at the COVID vaccine facility, she was told to go home, and someone would call to check on her. She felt a slight itchiness on the right side of her face. Her face looked very red, specifically her cheeks and forehead. She was so fatigued, she felt like she was drugged. She took Claritin. She couldn't fall asleep. She has extreme GERD and would wake up with an extreme racing heartbeat. She also had this happen prior to the COVID vaccine. She stated she takes Omeprazole, basically the prescription version of Prilosec. She stated her GERD is inflammation-based and the COVID vaccine must have triggered the GERD. Eight hours after the COVID vaccine, she fell asleep for five minutes, woke up, looked in the mirror and there was a big, red rash area on the whole right eye area on the right side of her face above her eye, but not to the top of her forehead. She hasn't been diagnosed with the cause of what is going on with her right eye. She does have right eye proptosis prior to vaccine so maybe the whole right side of her face was targeted because she has immune issues on that side prior to vaccine. On the next four days, she got zero sleep and had a hard time sleeping. She went to her primary doctor on Monday (unspecified date) and her blood pressure was 140-something over 80-90. Five days after the COVID vaccine, her blood pressure returned back to normal. This whole time she was taking Claritin. She could feel tingling feeling through her arm. She almost feels like she had been shocked or electrocuted. She had that continually feeling in her face and arm since the COVID vaccine. She did see an allergist who stated caller should have been given an EpiPen immediately. She has never used and EpiPen before. She saw the allergist seven to eight days later. The allergist took blood to see if there was still a histamine response, but her results were normal. She was still feeling those weird feelings of being electrocuted or shocked. The right side of her face is hypersensitive. It comes and goes. She did see her endocrinologist who stated maybe it's a neurological response to the COVID vaccine. She stated the doctor had seen what happened to her before, but it didn't last long. This doctor saw the face would go away after thirty minutes and reporting the ones that come back for the second time, their high blood pressures lasted for twenty-four hours. Her high blood pressure lasted for 5 days. The past couple of days her blood pressure has been very low and then high. It is all over the place, which is not normal for her. The outcome of the event "blood pressure went up/blood pressure was 153/92/her blood pressure was checked three times and the lowest was 142/90" was recovered, and unknown outcome for the remaining events. Information on the lot/batch number has been requested.
