Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. Anxiety is fear of something which actually is non existent. In this case you are worried about your health and this can be called health anxiety or hypochondriacs. But you have nothing to worry. The chest tightness is due to the acidity related to anxiety. Exercise well, include ginger and garlic in your diet and ignore the chest tightness feeling and the problem should vanish within a few days. If you require more of my help in this aspect, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe the needed psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck.
