I've read somewhere that it's normal for one side of your nose to be blocked most of the time, hence only allowing you to breathe through one side. Is this true? I find that one side of my nose is always blocked. Not completely blocked, I can still breathe through that blocked side, but with difficulty (the other side is usually fine). Sometimes it switches. Sometimes they're both unblocked (I assume that's when I don't notice it).

I don't have a runny nose, haven't had hayfever recently, not sick... I don't feel anything except for that blocked bit. Is this constant blocking of one side "normal", or should I be worried?

Oh, I might add... when I look inside my nose, I notice that the blocked side is more "swollen" than the other side (kind of like what you get when you have a flu, I think).

Thanks
