Additional information: NDC number of Covid Vaccine: Unknown, UPC number of Covid Vaccine: Unknown, Reason for no lot number: of Covid Vaccine: Complainant hung up abruptly/transfer incomplete, Expiry Date of Covid Vaccine: Unknown. The consumer stated, I had first dose Pfizer Covid shot (vaccine) and I had a bad reaction. I have been transferring three times, am I talking to the correct person? (Further not clarified the previous Department name. Hence, captured as initial report in the tab). When probed for the concern, consumer stated, I have arthritis and I also have a problem with my heart nothing serious, but vaccine did cause in my body to trigger and impact to all my medical problems. Muscle in my heart was very painful, trouble in breathing like it was that painful my doctor cannot even touch me in that area. He sent me to the Emergency Room after the Cardiogram, I never had arthritis attack in my life it looks like I have boxing gloves, my ankle was all swollen in both hands and also my feet, my ankle and my feet. I was unable to lay in bed because my hands were so swelled that I did not have blood circulation in my hands. I have to get out of my bed and stand up. I did not sleep even 5 minutes, that is how bad, it was. This vaccine caused this problem within days having this vaccine I started feeling pain in my elbow, the pain started in my elbow and went into my arms into my hands and from everything went wrong. How am I supposed to have second vaccine when my body is acting this like they did not tell that the vaccine is safe? It is not safe for everyone, I have someone that use to play guitar and after the vaccine on the left arm he cannot even press their cords, the string because he has no strength in his hands to even press to play his guitar. My sister cannot even raise her arm. Why do they not tell people that the vaccine is not safe, did not do any research about medical history, some people have "died" (further not clarified) after the vaccine. Vaccine is causing me so much harm and nobody is giving me any answer, it is something like conspiracy (further not clarified) because they are not telling that vaccine is not safe, vaccine really very hurts me.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
