you've never had spinal and/or brain damage, have you? Do you know what I'd give for a month of pain free living? I'd pay 20k a month for it!
I'm not putting anyone down for trying this procedure, I'm just telling you what I remember.
I've had a Caldwell-Lucs procedure under local anesthetic & ethmoiditus, so YES, I KNOW what pain is. And I know that opiates don't work very well. (It's beyond me how anyone can get off on oxycontin.)
Good luck and do your research. I was cured by a smart-as$ Indian surgeon who's not afraid to do cutting edge surgery. Even so, I was in pain for six months after the last operation (laser ethmoidectomy).
My best advise to you and anyone in a nasty medical situation: find the doctor that other doctors are jealous of. If, during a consult, a doctor says, "if you go to such -an-such, he will do surgery, but you won't get better" THAT'S the doctor to go to.
Been there, done that. It works.
