shooting chili up your nose

Would you shoot chili up your nose? I mean capsaicin, the active ingredient in hot chilies. I think that I would have to be desperate to do that. But my husband David has been doing that for about a week now. He has chronic recurrent sinus problems and infections and has had two sinus surguries in the past 10 years. But he keeps having more infections and problems. He used over the counter Afrin, but that can't be used for too long. So he's tried a dilute solution of betadeine, nasal rinses with salt water, steam, and just about everything else that can be tried. Now it's the active ingredient in chilies. His physician recommended this, he didn't come up with this on his own. I have a few recipes that use hot chilies and I'm always careful when I cut them up, but I always end up getting some on my finger and touching my lips or eyes, then having burning for a few minutes to hours. I don't know if I could shoot that stuff up my nose. I wish that I could somehow cure his sinus problems. His ear nose and throat specialist my consider a third surgery if he doesn't improve.
