face got hot; she felt the pressure in her head all of sudden like a big air bubble trying to blow up; pressure in both her ears; excruciating pain from the top of her chest down to her right breast; excruciating pain from the top of her chest down to her right breast; excruciating pain that went down from her neck to her right breast; nauseous for a couple days; D-Dimer was also elevated, it was 0.7%; kidney function 62%; This is a spontaneous report from a contactable consumer (patient) via a Pfizer sponsored program Support. A 62-year-old female patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection), via an unspecified route of administration, administered in left arm at age of 62 years old on 15Apr2021 14:30 (Batch/Lot Number: EW0153; Expiration Date: Jul2021) as single dose for covid-19 immunization. Medical history included ongoing high blood pressure/ hypertension. The patient's concomitant medications were not reported. No additional vaccines administered on same date of the Pfizer suspect, no other vaccinations within four weeks prior to the first administration date of the suspect vaccine. With the first dose patient felt nauseous (2021) for a couple days and she also felt excruciating pain from the top of her chest down to her right breast. She also felt pressure in her head and both of her ears. After receiving first Covid 19 vaccine on 15Apr2021, patient sat for 30 minutes and then she went to the store. Standing in the check out line was when she felt the pressure in her head all of sudden like a big air bubble trying to blow up and in both her ears. She went back to her car and sat there and that was when she felt right where her neck connected to her chest, in the middle, a little bead in the center, excruciating pain that went down from her neck to her right breast. The pain caught her off guard and she thought she should go to the emergency room, but she did not go to the emergency room. She had just received the Covid 19 vaccine and she was told that she can't take any medications or antibiotics after getting the Covid 19 vaccine for so many days. She went home and she prayed. She stayed at her house. She did call the facility where she received her Covid 19 vaccine and she was told that some people did experience a weird pain after receiving the Covid 19 vaccine and then the pain went away. The facility told her it was her immune system reacting to the vaccine. She decided to let it go but she did call her doctor and got an appointment for Tuesday, 20Apr2021. She had blood work done (in 2021) and that turned out ok. Then on Thursday, 22Apr2021, she had to cancel her appointment at her beautician because she had to pick up her grandchild. In her car, her face got hot and she thought did her air condition malfunction. Her air condition was fine. Then it happened again, her face got hot in her car again. She called her doctor and her doctor told her to come in and be seen. She was seen by a nurse practitioner (in 2021) and had an EKG and she did some other blood work. Her Troponin was normal but her kidney function had dropped. Her kidney function was always pretty good even though she has high blood pressure. Her kidney function was always around 92% or 108% but it dropped down to 62%. Her D-Dimer was also elevated, it was 0.7%, she stated normal range is 0-0.5%. She received a call from her doctor's office while she was at work and she was told to go and have a scan done (in 2021). She had a CT scan of her heart and lungs. That was negative. Why was her D-Dimer elevated, she was told it could be inflammation or there are so many things that could cause it. Her D-Dimer was just mildly elevated. Maybe she should have gone to the emergency room after the first Covid 19 vaccine but there was stuff she didn't know and she didn't know what the emergency room staff was going to do and she's just had this Covid 19 vaccine and its kind of like Jeopardy, she just didn't know what to do. Meaning she was afraid to take any medications or receive any treatments because she had just had the Covid 19 vaccine. Treatment information was not reported. Vaccine Administered was not at Military Facility. Physician Office visit requested for the events. No Emergency Room visit. The outcome of the events was unknown.  Follow-up attempts are completed. No further information is expected.
