Hello Doctor, My father age, 65, recently travelled to Canada and develop a new cough (dry & mucus). Also his temp reach to 100F during the day. He got minor heart attack in sep 2002 and implanted with 3 stent. My question is do we need to go for any specific test in Canada? Is it normal to develop such symptoms. His bp remain in between 125-140/80-89mg/mm, spo2 98-99, heart beat 69-79per/min. Thank you in advance for you time to consider this query.
