Hello and welcome to Healthcare Magic. Thanks for your query.
Your symptoms are indicative of an anxiety
disorder and you seem to be having a lot of health anxiety. Now, you have mentioned clearly that all medical tests have turned out negative, including EKG, chest Xray, blood tests and a thorough physical examination - which rule out any possible cardiac cause for your breathing problem.
It is important to understand that anxiety can present with not only psychological symptoms but also with physical or somatic symptoms. Please have faith in your doctor who has done a thorough and systematic evaluation and told you that you don't have heart failure
. These doubts, worries and preoccupation with health problems itself is actually a manifestation of anxiety. Please seek the help of a psychiatrist
to manage your anxiety-related problems.
Wish you all the best.
Dr. Jonas Sundarakumar
