Rhinoplasty/turbinectomy

Hello. I am new to this forum and i am hoping someone out there can help put me at ease and answer a couple questions. First off, I am scheduled to have rhinoplasty and a turbinectomy done mid November...I am not as scared about the rhinoplasty (just fixing a bump on my nose) as i am the turbinectomy. The thing is my doctor says i have enlarged turbinates and a slightly crooked septum which effect my 'breathing' and he wants to take care of them. However, I do not have difficulty breathing, the only problems i told him i have on a regular basis are sinus headaches and constant post nasal drip and i am unsure if these are caused by the turbinates or not. He thinks the turbinates are more of a problem than my septum. What scares me is all i have been reading is how bad it is to remove a turbinate and how you will forever suffer from a dry nose and throat and your nose wont be able to warm the air or humidify it when you mess with the turbinates...it can pretty much make u uncomfortable for life. Is this true? Is there anyone out there who has had this done who can verify these issues so i can tell my doctor not to do it before i make a life altering mistake? I've heard the main symptom of problem turbinates is not being able to breathe, but i have no problem breathing. Are sinus pain, headaches, and a lot of post nasal drip considered symptoms of problem turbinates as well? Id REALLY appreciate any help!! I am getting really scared about having this done and screwing up my nasal function forever. Thank You in advance.
