I am a 33 yrs old with CF (very mild case) and I have had 3 nasal polyps/sinus clean our surgeries. Lots of bleeding my first surgery. I have lots of damage to my sinus (bone) due to the polyps being left along for so long. <img src="i/expressions/face-icon-small-disgusted.gif" border="0"> Other surgeries were very minimial and much easier to recover from. I haven't had a sinus surgery for over 10 years and doing fine so far. <img src="i/expressions/face-icon-small-happy.gif" border="0">
