I do not know if PN can be made worse by the test, but I don't think so. Sedations would be another issue if you ever had to have it. Pillow, and maybe IPOD with a book on tape will make time pass quickly too. Not sure I could stay and watch some boring TV show. If it was Nova or discovery, well that would hold my interest. Maybe they have DVD that you could bring your own to watch. just a thought. ginnie
