It is in the left chestarmpit area.  <response>: Thanks for contacting ChatDoctorI am sorry to hear that your overtook the number of antibiotics. This will not cause any side effects, but the course is now shortened by 2 days. If you are still having symptoms at the end of your therapy then I recommend you call your doctor for an extension of the antibiotic. Hope this answers your question.
