Hi. Thanks for your query. Noted the history and understood your concerns. This is the confusion one gets when you do not get the confirmed diagnosis. Complete cardiac check up is the most important thing that you should get as Palpitation is one of the major complaints along with numbness, fatigue, nausea, vomiting and dizziness. I would advise you the following in such a situation: Cardiac check up as mentioned above. Blood tests particularly for thyroid functions as Thyrotoxicosis can cause similar problems. Surely anxiety and stress can wither be the cause that is instigating factors or at least enhancing factors and who wants to accept. It is better to get counselling and management from a Psychiatrist to get the things either ruled out or confirmed and get treated accordingly if found. Medical field depends upon the facts hence get the proper diagnosis and management and you will be fine, Internet searches by contacting the sufferers will not get you anywhere nearer the diagnosis hence should not contact such unilateral interactions and that too with the patients as they are not Doctors and you can get further confused as the person wants to listen to the things which he wants to.
