I have a history of nasal polyps. The surgery is minor, can be done in a doctor's office usually with a local anesthetic. It's not my favorite way to spend an afternoon though. An instument is inserted into the nasal passage that is essentially a fine wire noose. The doctor will loop it over the polyps one at a time and draw it tight to snip off the polyp. Then they cauterize the inside of the nasal passage. You hold a metal plate between your hands. An electrical current passes through your body. The doctor has the other terminal, which is an instrument he inserts into the nasal pasage where it touches the wall (where a polyp has been snipped off, it literally cooks the exposed flesh to stop the bleeding. The sizzling sound and smell of burnt flesh is delightful.
When a person has polyps, they tend to recur, for they are a complication of upper respioratory allergies. The inside of your nasal passages are just very sensitive and react to allergens by developing the polyps. He'll probably go on Flonase or some other steroid based nasal spray. Steroid based nasal sprays are well tolerated by most people and have few side effects. Because the medication is applied directly to the site of the problem, very low doses are used. It does not get into the system and is not a risk to your liver, kidneys or any of the things you worry about with prednisone, which is taken internally and is systemic. I was told I would have to take a steroid based nasal spray the rest of my life, but I should never have any kid of problems from it. I use Flonase regularly now and have no problems. I'm not bloated. My liver is not at risk. It doesn't affect may ability to exercise. Shawn Andrews will be fine and able to practice two days after his surgery, if not the next day.
