Hello there, It is very unfortunate to know that you are suffering from difficulty in breathing. However, most probable cause for your discomfort could be your acidity and others being stress, mental as well as physical, and overexertion. You need not worry with respect to panic attacks. I would request you to get your blood pressure checked regularly as, it may be the hidden cause behind it. I advise you to see a homoeopath. Hope this helps. Please feel free to ask any other queries that you may have.
