HI Thereafter reading the details provided by you, I would like to advise you to personally consult a cardiologist for evaluation as the symptoms you are describing here goes in favor of having a congenital heart defect which require a ECHOCARDIOGRAPHY to be done for evaluation and further work out plan. I wish you good health
