My vocal cords start swelling after I talk for an hour or more unlike other people. Does post-nasal cause swelling of vocal cords? My doctor suggested that I have anti allergic. Does post nasal cause mild changes in voice? This is the only question I wanted to ask.

Yes, it is possible that post-nasal drip may cause swelling of the vocal folds and associated vocal changes.
