Ask away! It's perfectly normal to have a zillion questions!
I've heard of some people having some difficulty swallowing, but I've never heard of anyone who couldn't swallow at all. That doesn't mean it hasn't happened, I just haven't heard of it. I did and still do have some numbness in my tongue that can make me choke on things if I am not careful, but it certainly hasn't stopped me from eating/drinking/talking... I certainly wouldn't expect to be able to chug a beer or anything (good thing I'm way past college age, huh?), but other than that, I don't think I'm limited at all.
I would think, and I could be wrong, that if your hypoglossal nerve isn't manipulated too much during the surgery and the AN isn't adhering to it, it wouldn't be a real problem. Maybe it's just a case of your doctor giving you all the possible post-surgical problems, no matter how infrequently they actually happen.
What surgery are you having?
