I can agree with you on this because I have had sinus problems all my life and I have used the sinus rinse, and I can say it does help. But I had been using nasal spray for my dry inflammed sinuses but lately I noticed recently I haven't had any nasal drip or pain in my sinuses for the last few days. Since taking some extra probiotics I noticed a difference when I took one in particular that my sinuses started clearing up. It's been helping me with my yeast problem, but that made me realize my problem with nasal problems and allergies has been due to problems with Candida. Keep using your nasal rinse, It does help.
