My daughter is 15 years old and plays water polo. She occasionally experiences severe chest pain during hard exercise - like an intense butterfly set or working with medicine balls. She s had an EKG and lung capacity test and both were normal. What could be causing this pain?
Hello, As you explain the history sometimes gastric reflux might be the cause of her pain. Discuss with her doctor, please.  Hope I have answered your query. Let me know if I can assist you further.
