Post nasal drip: Usually with post nasal drip it is thin and clear , can have the clearing of throat and change in voice. Typically with sinus infection the discharge is thick and yellowish/greenish in color. Also you may feel pain around the nose and forehead area. Can also have a mild fever with sinus infection. Sounds more like post nasal drip in your case.
