Threee months ago I had Flu which precipitated in Asthma. This has been my story for last many years but this year my condition does not seem to be improving. I have had all kinds of Blood tests , Allergy test , X rays , Lung function test and Ct scan . All are normal. I am on QVAR, Salmetrol 50 , Theodur
9 THeophyline) and I still feel shortness of breath. Doctor believes it is Asthma but at time I feel he is confused since MY PEFR values are approx 540 .
Can some one guide me ......
