Thanks for youe query.You had a choking
sensation in your chest 10 days back and you got all the test done including stress test
and reported to be normal Whatever you are thinking about is nothing but an anxiety
what is called as Cardiac Neurosis
.Pl stop worrying about what is not in existence..Do mild exercises and meditate for 30 minutes everyday and relax your mind.I am sure things will settle in 2-3 weeks time.
