Neti Pot

Has anyone ever used a Neti Pot? I went to the doctor about my headaches. She prescribed a whole bunch of crap. At the end of the appointment, I asked her if she could just look in my sinuses, because the chiropractor had told me that he thought my headaches might be sinus-based. I knew I had a deviated septum and an enlarged right turbinate, based on past x-rays and my recent MRI. But the doctor said my right sinus looked terrible a I also have a large polyp in my right sinus. She gave me Biaxin for 10 days, a steroid pack, and recommended a Neti Pot and some other nose sprays. Come back in a month and we'll get a CT scan, and I might need to be referred for sinus surgery. An ENT had suggested a surgery 10 years ago, and I could not stand the idea of the surgery. But I don't know, now, it might be worth it if I could get of these headaches.
So I get the Neti Pot, and when I follow the directions it works perfectly one the first side, but the other side, there is no flow out. It just all goes down my throat and chokes me. I guess that side is just blocked because of all the problems? Or am I doing something wrong?
PS After my facial last night, my skin kept getting more and more inflamed, and this morning I woke up and it was painful and beet red. I am glad I did not do it right before the wedding.
