Yes, I had the in -office one done to me today, he sprayed nurabing medication into my nose and it went through my nose and down my throat, after about 5 minutes to get it nurab he put a thin tube up through my nose and into my throat. He looked around in my throat and then he slowly brought it back up. It only hurt because my sinuses were swollen and he was having to fit the tube through there, I could barely feel it in my throat and breathing was normal.
