Tightening in the chest can be a symptom of a heart problem, especially if accompanied by other symptoms such as back or arm pain, shortness of breath, and pain after exertion, explains Healthline. Anyone experiencing new chest pain of extended duration should seek emergency medical treatment.
Tightening in the chest or chest pain is not always related to the heart. Chest symptoms may also be caused by gastrointestinal, muscular and lung-related issues, Healthline points out. Chest pain is likely not related to the heart if it occurs along with symptoms such as a sour taste in the mouth, a rash, feelings of panic or hyperventilation, or if it dissipates or worsens when the position of the body is changed.
