Feeling chest tightness but breathing normally may be normal, but it may also be abnormal and caused by pathological factors.
Sometimes mental factors can cause feeling chest tightness but normal breathing, when there is no pathologic disease, through mental adjustment, can recover by themselves.
However, some diseases, such as severe gastroesophageal reflux, can cause the feeling of chest tightness, but there is no hypoxia and breathing is normal. Another example is patients with coronary artery disease due to myocardial ischemia, which may also lead to symptoms of chest tightness, but if there is no combination of complications such as cardiac insufficiency, breathing may also be normal. If the above mentioned diseases are present, they need to be actively dealt with.
Therefore, if you feel chest tightness but your breathing is normal, you also need to consult a doctor in time to investigate the cause of the disease and individualize the treatment.
