Sorry about your experience, I can relate (commented elsewhere here, though the underlying reason was not a polyp). Regarding association of whispering with throat pain - it comes from (much more common) experience with viral infections that inflame the throat and chronic laryngitis is nothing like that. In my case, I had a ticklish sensation for couple of days and then nothing at all, no pain, but the voice disappeared. Also, it turns out that whispering was even harder than vocalizing because - paradoxically - whispering requires more control and effort from vocal cords than vocalizing.
