I tried one of these rinses a few weeks back Al when I had a real bad sinus infection. It only worsen the situation to the point I had to go to the dr for antibiotics & a steroid shot.
When I did the rinse, I guess some of residue remained in my nasal passages thereby causing more infection & gunk in there. Even up to 2 or 3 days after doing the rinse, everytime I bent my head down, bloody discharge would come out of my nose! It was terrible!
Same thing happened to hubby after he tried the neti pot a few times.
