What Causes Cold Sensations In Throat After Using Candibiotic Ear Drops?

I put candibiotic ear drops in my left ear and suddenly I felt some coldness in my throat and hence through breathing pipe.It never happens in case of right ear.This happened twice when I took the dosage.Is there any serious problem??Is there some kind of leakage between my ears and throat??Are those drops harmful in anyway if got into stomach??Plz help!!
