I figured I'd check here with you friendly folks before I google it. My daughter has serious issues with her sinus. She's had pneumonia twice as a toddler. Allergies and shots til she was 15. She was good for awhile, now she's suffering - like she has a cement block in her sinus. I'm trying the Neti pot ritual, but not sure of the ratio of warm water and salt, does anyone know? She is desperate, and wants surgery, I don't want her to do that unless it's absolutely necessary. Yikes, any ideas?
