I'm 40 yrs old and just have been diagnosed with asthma. I went to the doctor because I had a cough that wouldn't go away after a cold. I'm been coughing for 3 months now and don't get any relief from meds. I'm on Advir, maxair, claritin, and sigulair. I sleep fine at night and don't cough, which I think is weird. I keeping going to the doctor and they put me on antibiotics for a sinus infection and prednisone for inflammation. The cough is usually dry, but has been productive at times. I'm a non-smoker and feel fine most of the time. Any suggestions would be appreciated!
