Hi thanks for contacting HCM... You have only constricting chest pain.... So first rule out cardiac cause by .... /blood pressure checking / ECG / tread mill test.... If coronary artery disease there like angina then nitrate given sublingually... If needed angiography might done... Second if your ribs tender to touch it could be costochondritis.... Brufen given for it.... You are doing three job , by which you can have stress and that can lead chest tightness.... Try to avoid stress... Yoga and psychiatric counselling useful.... If still cause not clear chest x ray and auscultation done for rule out respi causes ..(although chance of it less) Take care
