Breathing Difficulties, What Could Be The Reason ?

I had respiratory difficulties last year and after undergoing a blood test, my doctor told me that I had eosinophilia. I got treated for it and symtoms vanished. I even got a PFT done which showed normal results. Six months later I got those symptoms again and my doctor after examining me suggested it is bronchitis. I was then put on inhaler treatment. I am using a combination of Beclomethasone Dipropionate 100 mcg and Salmeterol Xinafoate 25 mcg. I use it only once at night (1 puff each). For the last 1 week, I am using it twice daily (3 puffs and 1 puff). What could be the reason? Could this be Asthma.
