She added 4 days after vaccination, she experienced "heart palpitations, she could feel it, and heart flutters". She specified these symptoms started on 22Apr at noon, then the next day she had it again, but it "lasted longer" than the previous day, and it "lasted all day long" the following day. She said she "started feeling better" this past Saturday, 1May2021, then on the following Sunday she was even "better", and Monday through today, Friday she has not experienced the reported symptoms. She explained she started a beta-blocker in 2013 and specified she would take her 150mg of Metoprolol daily when experiencing her symptoms. She said her primary care doctor (PCP) has offered to increase her beta-blocker if her symptoms would worsen, and that her palpitation could be due to anxiety. She explained she disagreed with her PCP. She mentioned she has not experienced these symptoms when feeling anxious in the past. She added she cannot rely on her PCP and is attempting to change PCP. She explained she had gallbladder surgery on 23Dec, which she "initiated [herself] because her PCP didn't know where [her] pain was coming from". She explained her PCP recommended her to get the second dose of the vaccine and said, "it's better than nothing or [she] won't be immunized". She mentioned her cardiologist, whom she is scheduled to see on 13May, said: she should go to the ER if her symptoms worsen, and she should get the second dose "if [she] feels comfortable". She explained her cardiologist sent that message to her through an unspecified intermediary after she informed him of her side effects from the vaccine. She specified she failed to obtain her cardiologist's recommendation on getting the COVID-19 vaccine prior to being vaccinated." She also mentioned she cannot take the Flu vaccine since she had a terrible experience the fourth year, she took it. She explained she took the flu vaccine for 4 consecutive years, the first year she was fine but the following year she reacted, and her reaction worsened after each year. She asked if she should take the second dose of the vaccine after experiencing side effects from the first dose. She explained she is left alone to make that decision and needs guidance. She started a beta blocker since in 2013. She did not have any heart problems since 2018. She mentioned that throughout her symptoms she has been continuing to take Metoprolol 150mg daily. She spoke with her Cardiologist, but did not get ahold of him directly, she got a message through from someone else, unknown if nurse or who; but the Cardiologist mentioned if she feels uncomfortable taking the second dose of the Pfizer-BioNTech Covid-19 Vaccine then not to take it; and mentioned if symptoms continue or worsen she should go to the emergency room.
