Im having chest pain. at first it was on my right side and now its on the left side?

Chest wall pain: Jordan, your pain is likely from the muscles or bones of your chest wall. This can sometimes be related to injury, sometimes not. Dangerous causes of chest pain are unlikely in a 19 year old without chronic health problems. If your symptoms worsen, you develop shortness of breath, or they don't go away, see your doctor. Hope this helps!
