Thanks for your question on Health Care Magic.
I can understand your son's situation and problem.
Yes, you should definitely
consult doctor for him because continuous
chest pain on exertion is commonly seen in cardiac and Pulmonary diseases.
So better to consult doctor and get done
1. Ecg and 2d echo
2. Chest
x ray and PFT (Pulmonary Function Test).
Ecg and 2d echo are needed to rule out heart diseases.
Chest x ray and PFT are needed to rule out lung diseases.
If all these are normal then no need to worry much for this.
Sometimes
musculoskeletal pain can also cause similar symptoms.
So no need to worry for this but better to rule out heart and lung related diseases.
Hope I have solved your query.
Wishing good health to your son. Thanks.
