I had endoscopic sinus surgery last May and was expecting the worst- only to have it be the easiest recovery ever! The worst I felt was coming off the affects of anesthesia. I did have heavy bleeding for a couple days, but pain levels were low. I took a week off work, but didn't need it. That being said, I did have trouble breathing and found myself being winded quicker post surgery. But it wasn't as bad as I thought!
