Good afternoon Everyone!
BJD, I had that problem recently when I contracted a sinus infection. I was antibotic for 8 weeks and prednisone for 2 weeks. I had acute asthma attacks also. I would cough alot and I would cough out as much of the mucous as I possible could. Try not to swallow the mucous ( sorry so gross) the more of it that you can spit out the better. I tried a cough syrup. That helped to make the mucous thinner, and easier to cough up and out. A nebulizer is also a good idea. Medication is turned into a fine mist. Advair Diskus is the best controller asthma medication I think. It is for me anyhow. Could also try turning on your shower real HOT. Let the bathroom steam up with the door closed. Then, sit in the bathroom and breathe in the air. That will loosen up the mucous. Those are some suggestions that I know. Hope, that helps some. Good Luck. Best Wishes to you.
