Chest Pain: Chest pain appears in many forms, ranging from a sharp stab to a dull ache. Sometimes chest pain feels crushing or burning. In certain cases, the pain travels up the neck, into the jaw, and then radiates to the back or down one or both arms. Many different problems can cause chest pain. Because chest pain can indicate a serious problem, it's important to seek immediate medical help.
