Hi Nit, WELCOME TO HCM. From the symptoms that you mention, it is unlikely that you have a heart disease. Since you have consulted a doctor and he did not say that you have a heart disease, then you can rest assured that you have a healthy heart. If you still suspect that you may be having heart disease, then you should consult a cardiologist, get a echocardiography done, which will clear your doubts completely. Wish you all the best.
