Brutal... I have been having pretty serious sinus problems for a while now. Doctors keep telling me there is nothing wrong and blaming it on allergies (which I don't have). I get bad sore throats (supposedly from a constant post-nasal drip), earaches that last weeks at a time, and headaches... i am supposed to have my 4th trip to the ENT in the next couple of weeks... If I go under the knife I want to go Zate's route and get any potential problem areas taken care of.
