bacterial infection
"I have COPD and other lung issues. For two weeks I received two shots a week. At first it seemed to help with little side effects. By the third shot did not seem like it was working anymore. Fourth shot caused severe side effects. I broke out in itchy  rash head to toe,  my throat was starting to constrict combined with a "sick" feeling getting worse as day went on.; Ended up in ER with throat constriction and difficulty breathing. Several hours of oxygen and Benedryl    I was released. I will NEVER take this med again. I still have the lung and heart sac infection!"
