Unfortunately, a long bout with a cold, virus or bacterial infection results in damaged membranes within the sinuses, nasal passages, and/or throat. The longer a cold, or infection, continues the more damage is done.
So...... the damaged sinus, nasal or throat membranes are frequently prone to cause irritating symptoms, or become reinfected after the cold, flu or infection goes into remission.
Until these membranes heal completely, they will continue to cause problems, IMHO.
Note that these are only theories of mine (a fellow patient) based on personal experiences, and that I am not trained or educated health care. I have merely learned how to permanently cure myself of recurring sinus/nasal infections.
Take care, best of luck, and I hope that you get your current health problems fully and quickly resolved.
