burning sensation from her chest to her abdomen and then to her back; burning sensation from her chest to her abdomen and then to her back; burning sensation from her chest to her abdomen and then to her back; sometimes on her back it feels hot; This is a spontaneous report from a contactable consumer (patient husband). A female patient of an unspecified age received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), via an unspecified route of administration on 21Mar2021 (Batch/Lot number was not reported) as single dose for COVID-19 immunisation. The patient medical history and concomitant medications were not reported. The patient received her first dose of the Pfizer COVID-19 vaccine on 21Mar2021 and since then she been experiencing a burning sensation from her chest to her abdomen and then to her back, they had seen a physician and had done testing but can't find anything, including a urine test. It was reported that the patient had the Pfizer shot, the Pfizer vaccine, and then between then and now she had been having things happen. She had been having chest pain with her chest burning and she needed an ice pack on the chest and on her neck she felt really hot. It was the weirdest thing, the body temperature was not high when measured it in the mouth, it was not high. It was like an internal burning and a very long time it had been - more than 30, 35, or 40 days. They went to see the physician and the physician had no idea. The caller thought he would call to see if Pfizer has any idea. Caller states the body temperature was not high, it was not chest pain and was just like a burning from the chest down to abdomen, it was very weird, and sometimes on her back it felt hot. The physician did blood work and urine and did not find anything - nothing. It had been to the point that her feeling was there and she could not even wear clothes. Normally, they wear a t-shirt and normal things, but she just felt very hot and she could not wear anything. He was looking for recommendations on how to treat these symptoms and if these symptoms had been reported. His main purpose was getting help with her because it had been more than 30 days since she got the vaccine on 21Mar2021. Caller states since today is 02Jul2021, it had been 40 days. Caller states that this was her first vaccine, and that she could not get a second shot. She was not agreeing to the second one because the first one almost killed her and had caused problems. They did not know where to go. This vaccine thing was so new and there was no specialist or anything. He knew a pharmacy does not or maybe do not care. He called them back and tried them but they have no idea either. He asked what was supposed to do or what they could do and could they tell him if this is side effects. Caller wanted to know they could give him a prescription. Caller was advised to seek help from physician to address medical advise. The caller was informed that they did not find information regarding an adverse event of burring in chest or abdomen. As the Prescribing Information does not include all adverse reactions that have been reported or that may occur, advise to consult with the doctor/healthcare provider about what the patient have experienced/are experiencing. Pfizer does not provide any recommendations regarding the management or treatment of potential adverse events/reactions/symptoms that a patient /consumer may experience. They were advised that the doctor/healthcare provider is in the best position to advise them about the appropriate action to take as their doctor/healthcare provider is most familiar with their medical condition, clinical history, how their treatment has been conducted and any relevant information to their specific case. The caller added that they already visited a physician, and they are at a dead end and they did not know because they were at an end. Caller states he would try to talk. Outcome of the events was not recovered.
