After one of my closest acquaintances who took 2 doses of the J&J vaccine started having chest pain and debilitating dizziness about 9 months post booster, I wanted to hear from the community on whether you are seeing the same thing amongst your family and friends. The saddest thing is, that he was vaccine hesitant, but did it so he could travel to see his wife in India. Now he is on a heart monitor and has a 30 minute episode daily of chest pain and dizziness. As of yet, they haven't found the cause, but heart inflammation fits his symptoms perfectly.
