I Have Asthma And Take A QVAR Inhaler Twice A

I have asthma and take a QVAR inhaler twice a day. But since getting a really bad cold ( bronchitis maybe?) a month ago, I haven't been able to quit coughing ( not a productive cough) Breathing is hard and I cough all the time. And my emergency inhaler doesn't seem to help when it gets bad. And I'm so very tired. I don't hav ea fever any more. I have had pneumonia 20 years ago.
