As far as PTC paper is concerned, it just contains a chemical to test if people with certain genetic traits can taste it. Of all the studies and tests done with it, there has been no real cases directly relating it to the cause of a throat sickness or inflammation. Now, as for your throat, it could have been you inhaled or consumed a type of germ soon after you tried the PTC paper or a germ was ON the PTC paper itself and entered your body when you tasted it. Like I said, there's no direct connection between PTC causing throat injuries or illness at this time.
