Been diagnosed with non allergic rhinitis, feline dander, housedust etc allergies. Also diagnosed with excercise induced asthma in the 90's. About a month ago wheezing. Doctor has me on 50mcg fluticasone/salmeterol powder am and pm,plus albuterol every 4 hrs. I haven't been using rescue every 4 hrs. When I talk I start coughing and choking and have to spit. What is going on with treatment?
