I have been short of breath for 7 months and have seen a lot of specialists. they say either anxiety or gerd. the only thing they never ruled out was a pulmonary embolism. is it possible to have an undiagnosed pulmonary embolism for 7 months???

You would be dead if it was a pulmonary embolism. These can start small but progress rapidly (hours) until you are either fixed or dead. Find a life coach that can teach you stress management & relaxation techniques. During the process you may uncover the unresolved hidden trigger to your anxiety. Health fear is a common coverup of deeply hidden triggers.
