Hi thanks for contacting HCM... Here first rule out respiratory causes as you are mentioning congestion with chest pain.... Chest x ray done.... It will help in rule out bronchitis or other respiratory restrictive disease if present ... If needed spirometry done for pulmonary function test.... According to cause treatment done... If no significant respi causes found then yes stress is causative factor.... Avoid anxiety as it can lead panicity and pain... Yoga helpful. Consult psychiatrist for counselling .... If needed anxiolytic drug given.... Finally if chest pain increasing then ECG done for cardiac screening. Take care.... Dr.Parth
