Sharon - My son has had 4 surgeries to remove polyps. One time he was 98% plugged on one side. They do unfortunatley come back. After each surgery they do tell you to use just a saline rinse - probably like you got - to keep the nose moist. After his last surgery about 2 years ago - he said he would never do this again - they used packing this time and was older so affected him more. We started doing the Neil Med rinses daily shortly after his last surgery and Boy what a difference it has made! He loves how they make his nose feel and gets rid of all that gunk. He is 11 - I keep boiled water in a jar and he does it all himself. He knows if he misses a day he can tell - so he does them daily. I wash mine in dish water and let air dry upside down. I just wish I would have known about this after his 1st surgery and maybe some could have been avoided. Personally I think he has some polyps again - but as long as he can breath and is feeling good - I'm not going to worry about it. I just hope that your son likes the rinse as well as Tanner does - it helps alot!!
