Some common reasons for chest pain at 15 could be anxiety. Anxiety attacks can cause pain in the chest and affect breathing. The best solution for knowing why you are having chest pain is to see a healthcare professional. Monitor your diet and activity to see if there is a pattern. If the pain persist and you are unable to control the pain go directly to the hospital because even at a young age you could be having a heart attack.
