The second dose was ok for a few days and then she had a terrible reaction. She clarified, she could not breathe, and she thought it was her high blood pressure reacting. She read in the pamphlet about shortness of breath. Her reaction was terrible, and she thought she was going to die. It was a horrible experience; she could not breathe. Her doctor did not know anything about it. She had an appointment at University Hospital to get her covid vaccine. She thought it was her high blood pressure and could not tie it together. She did not go to ER or anything and states you know that pressure can go up and down, but her blood pressure was not going up and down. Her reaction occurred in the last part of July or beginning of August. Reported that she was not quite finished with it but she is breathing better. She is just now getting over it. For treatment she declined any, she did not show any signs of misbehaving and she was nowhere near the doctor. for other medications, reported she was taking her high blood pressure pills, iron and aspirin like she normally takes. Reported it was frightening and she had heart palpitations and she has never had that. She was no longer feeling heart palpitations, she only felt them previously for 3 nights when she would get up. Her head hurt so bad one day and she soaked a face cloth with alcohol, and it hurt all day long and then it went away. She did not know what brought that on. She was checking to see if her high blood pressure was unusual. She was reading about the vaccine. States it is a lot to put on a person. The vaccine has not even been tested; she could not believe people would be given something like this. She asked if there is anything she could take or do. Event did not require a visit to, Emergency Room or Physician Office. Prior Vaccinations (within 4 weeks) and events following prior vaccinations were none. She had family members get a different vaccine and they were fine. Relevant Tests done were none.
