I've been having a chest pain for 3 days. First day when I consulted a doctor​ he asked me to take an ECG and an abnormality was discovered. So he adviced me to consult a cardiologist. So today I consulted a cardiologist. He asked me to take an echo and he concluded that I have a small anterior muscular vsd with L R SHUNT which had from childhood itself. He told me that its not a big issue, so I need not take any medicine. But I'm​ still having some pain and difficulty in breathing.
