I have a question for you ukxmrv. I have sinusitis also with the pain and would love to find something that actually works. I was told by an allergy doctor that irrigating is bad because it can cause sinus polyps. I think he was referring to the machine used years ago, but I am not sure. Have you heard about the irrigator/polyp connection. Do you think your irrigator is not the same as he was referring to?
