About 15 years ago I went completely hoarse...no voice...It was determined I had polyps and they were removed....Recently I had a upper respiratory infection with cough and cold.  It is two weeks finished but I feel like I have a little phlegm in my throat and I try to cough it up.  The more I try the more irritated it becomes.

My fear is that I may have created a small polyp from the after effects of the cough....Is there anything I can do to clear it up, or make the tissue revert back to it's normal condition?.  It is definitely something I can live with and seems too small of an issue to have surgery on but then I worry will this little issue become cancerous. thank you
