I check my heart,ecg,echo,holter and stress test,all say that my heart is fine,but i still have a chest pain and left arm pain.what should i do ?

At 23: Risk of non congenital, non viral cardiomyopathies is low. Hence negative predictive value of negative Echo, holter and stress test will be near 100%. simply put cardiac disease is unlikely.May f/u with detailed description of the pain(type,duration and aggravating and relieving factors) weightlifting or any strenous sports? then also Anxiety!
