Additional information: Transferring agent stated, "I have patient on the line today and the reason for my transfer today is that she is having adverse effects from the COVID-19 Vaccine, she did clarify it is the Pfizer COVID Vaccine and she is experiencing hematoma on her arm a couple of days later after that it was swollen, bruises she got nose bleed as well and on 19th April that she was experiencing chest pain she went to ER and they were thinking it was cause of the COVID Vaccine as well." Consumer stated, "On 07Apr2021, I have the LOT number and everything of the vaccine I received for both of them on 07Apr2021, I got the Pfizer the second Pfizer shot and I developed a hematoma on my arm which was as big as a baseball. It was really swollen and I take blood thinners and on the next day on 04-08, I started getting a lot of nose bleed. I never get a nose bleed and so I called my doctors and asked what should I do and she said stop taking your blood thinners so I stopped taking the blood thinners and then may be after 7 days, I started taking my blood thinners again. So, it took about 3 weeks for the hematoma to go away on 04-19th, I had a huge chest pain, I have had open heart surgery before and I had to go to the ER because I felt light headed and dizzy. My arm hurt, my chest, I took nitroglycerine (treatment) and it made still little better but anytime I exerted myself it gets worse so I went to the hospital and they admitted me because they couldn't control my angina and my cardiologist did an angioplasty (Further clarification unknown) and he found that my 2019, I had a bypass of LAD artery with my LIMA artery (Medical History) and he found that my bypass had developed a huge blood clot and failed. So, basically I am looking at go in and having another bypass using my LIMA artery but the surgeon, the coronary surgeon that I talking he wanted me to call Pfizer to let you guys know because he said that that is so weird that it failed and the shot and everything and he just wanted you guys to be aware and you know that's what we wanted safety because I know that when I went in I had a lot of a questions and none of my doctor could answer. It says I shouldn't take it if I am on blood thinners but they said it is still better than you getting COVID so I went ahead and took the shot but actually now I have to get a bypass again. It might be from the vaccine, it might not be from the vaccine but the timings is just you close together there." Patient took Nitroglycerin, she was on now but that's because of the chest pain so that was on before she had the chest pain when she had the shot (Further not clarified). When probed of the event is still ongoing: Consumer stated, "Yes, because my By pass graph is now failed." Treatment: Patient took Tranexa (name not clarified). It was a medicine for her chest pain. Outcome: Consumer stated, "As in nose bleed and bleeding are gone, now it is just chest pain".   Follow-up attempts are completed. No further information is expected.
