My 16 year old son is having chest pain when he runs the mile or 2 mile for track.  He says it hurts on each beat and sometimes hurts above and below the heart.  He has been diagnosed with Vocal Cord Disfunction in the past and we had one Dr. suspect him of having marfans.  We had a visit with a cardiologist who performed an echocardiogram and found nothing wrong. He also told him not to go to the marfans clinic.  He is still having chest pains and is now unable to finish his track season.  Could the echo miss something?
Thanks for your question on Chat Doctor. I can understand your concern. Normally echo is done in resting condition. This kind of resting echo can be normal despite having heart disease. So stress echo should be done. In this, patient is force to perform exertion like running and then echo is done. If you this is normal then no need to worry about heart diseases. Sometimes simple musculoskeletal pain is the cause. So apply warm water pad on affected areas. Avoid strenuous exercise for few days. Don't worry, he will be alright but first get done stress echo. Hope I have solved your query. I will be happy to help you further. Wishing good health to your son. Thanks.
