8 days post septoplasty. Difficulty breathing?

I'm trying to be patient because I know there is still swelling. but in addition to the blocked nasal passages I have post nasal drip and a sore throat and it feels like I cannot get enough air. When I stand up I am extremely dizzy and tingling in my arms and hands. I cannot even walk across the room without gasping for breath and having to sit down. Is this normal?
