I suffered from sinus infections for years and finally had to have the surgery to clear them, as they were 99.9 % blocked. My doctor recommended that I use the Netti Pot on a regular basis after the surgery to help eliminate any other sinus problems and .... IT WORKED. Hubby and I use it at least once a week ( perhaps more in the winter and during pollen season ) and the sinus problems have ended for both of us. Hubby did not have surgery and his sinus problems are all gone too ....
Please give it a try, you will not regret it .
