Good Morning, I have a 20 year old son who is an athlete but has been been dealing with chest pains. He was previously diagnosed with asthma and was talking an inhaler . Back in October, we took him to the emergency room and was referred to a cardiologist . He has had several tests and they have come back okay. When we were at his primary doctor a few weeks ago, they mentioned it could be muscularskeletal...what type of doctor would handle that. Also, isn t that normally the result of some kind of injury or trauma?
