I have had 9 nasal surgeries on polyps. I am ddf508 and seem to have all the side effects of cf. Lungs and weight are strong but I get polyps all the time. my save your body some stress and avoid the steroids the doc wants to give you and just go for the surgery. Even if you do the steroids and the polyps shrink a little, they are still going to grow and you will still need the surgery. I try to put as little meds in my body as possible, they are not worth it. The surgery is not bad. I have easy surgeries and some where I woke up throwing up blood. I never woke up in pain, just irritated. After surgery, you will be fine in a day or two. I normally take a couple days off work and that's it. The worst of it is sometimes, you can scab up around the nostrils which is noticeable. It takes about 4 days and the scabbing will go away. Good luck, again save your body of the pills
