Welcome to HCM
We understand your concerns
I went through your problem description. I suggest you not to worry too much. You must believe your doctors. They are correct about your health. They might not have given you the details, but I suspect you have some somatoform disorder
. Severe chest pain
could just be your imagination. I mean it. Imagination can create problems which are non existent. Some patients of somatoform disorders even say they are without hand, when hand is very much available.
I suggest you need psychiatric intervention for hypochondriasis and anxiety. Do consult a psychiatrist
Hope this clears your doubts. Available for further clarifications.
