Hi thanks for contacting HCM.. Noted here only dull chest pain present ... So here two causes can be there .... - musculoskeletal pain or -cardiac cause like arrhythmia as fluttering present .... Respiratory cause less likely as no other symptoms present... Here get your blood pressure measured and ECG or echo done to rule out cardiac cause. Causative treatment done... If no above cause present then muscular pain could be there. For that rest done.... Analgesic can be given.... Hot pad can be applied.... Avoid strenous exercise..... Take care...... Dr.Parth
