The technique in
this manual involves bending over in
a hot shower. Obviously, if you bend over in
a shower, there is a slight possibility that you can get dizzy and fall down. You could possibly hit your head, get knocked out, or break something. It’s a tiny risk, greater if you are older, overweight, obese, or have reduced blood flow in your neck arteries, but it’s a risk you must assume if you want get rid of an otherwise untreatable sinus infection.
