Hello , how are you doing today ?   I ’ Ve been having trouble breathing lately .   Have you had any type of cold lately ?   No , I haven ’ t had a cold . I just have a heavy feeling in my chest when I try to breathe .   Do you have any allergies that you know of ?   No , I don ’ t have any allergies that I know of .   Does this happen all the time or mostly when you are active ?   It happens a lot when I work out .   I am going to send you to a pulmonary specialist who can run tests on you for asthma .   Thank you for your help , doctor .
