I am 51. female, very physically fit. I have never smoked. For a year now I have had episodes which start with a cough, usually in the evening. Then I get short-of-breath, have wheezing esp. on expiration. I had allergy testing done and have some allergies and chronic sinusiits. Finally ENT sent me to pulmonolgist. Pulmonary function tests were normal but she thinks I have asthma. I am on Xopenex inhaler and Quvar inhaler. Recently having more attacks and having to use the Xopenx more so she ordered antibiotic and 1 week of predinose. She wants to do a high resolution CT of the chest and methocholine test but it is very exspensive so I am trying the conservative approach first. Do you think I have been misdiagnosed? I am so healthy otherwise and don't smoke. But my dad and brother have never smoked and 1 now has severe asthma and 1 has COPD!
