Does anyone have problems with throat closing up while sleeping?

I have asthma and Bronchiestases with the asthma being silent for many years. Recently the asthma has made itself noticeable with breathing problems especially during the night. I am taking Symbicort but am still waking breathless often during the night with the feeling that my throat is closed up, sometimes clogged with mucus.

I am wondering if all the years of not treating silent asthma has led to more mucus membrane and narrowing of the airways.

Also concerned all the coughing and throat clearing has damaged my throat.

Any input would be appreciated. Thank you.
