Given your stature and chest pain likely cardiovacular related symptoms, you might have marfan syndrome. Marfan syndrome is rare and affected people are born with it. A connective tissue disease which can come with cardiovascular complications among others. Read about it and get the help you need from a professional. In my opinion detoxifying powders cannot help. I am a doctor but not a cardiologist. As one of the above writers said, hypertrophic cardiomyopathy has similar symptoms but your stature makes me really think you have marfan syndrome and we should watch out for aortic complications.
