This is one of those situations were symptoms of a medical condition can cross with symptoms of an anxiety condition. I would give it the 2 weeks or so, like the doctor said, and then see how you feel. Is there is no change then, it is most probably your anxiety kicking in. Just finish off the medication they can gave you take. We know it is not your heart. That is a good thing. Helicobacter pylori Mainly causes bacteria in the stomach. Can cause discomfort. Leave you bloated. Maybe some acid which could be causing the chest issues. The medication they gave you for it may clear all this up. Hence we have to finish them off before we know if it anxiety or not.
