Hello. I had sinus surgery this past October on the left-hand side and he suctioned everything out, including the infection. He did not bother doing the right side due to the risks. (I was totally filled up on both sides.) Unfortunately, just this week, I caught a chest cold, which is now moving up into the sinuses (yellowish-greenish mucuous w/some clear thick mucuous). I have been doing saline sprays, neti pots, and use a humidifier. I am worried I will need surgery again, but it is a moot point if this is going to keep happening every time I catch a cold (which it does.) Do you have any suggestions? Thank you. Very, very frustrated. Unfortunately, I am out of a job and going into foreclosure, so can not afford to pay. That's o.k., nevermind.
