To have pain in the chest is not normal. This can be due to acid reflux esophageal problems or heart related. The best way of evaluating is to go see your primary care physician tell him or her when the pain occurs, (before or after meal), exercise, strenuous effort, etc. Let your primary care doctor decipher where the pain is coming from and prescribe an appropriate treatment plan.
