My 38 year old son-in-law has been having extreme fatigue ,high blood pressure and anxiety. He has had an EKG which was ok, blood tests which were ok and put on blood pressure medication. Today he is having shortness of breath, weakness and coldness. My quetion is , if we convince him to go to ER,would he possibly be evaluated by a cardiologist?
