About a year ago I went to have my deviated septum fixed. It was a very simple procedure but after I was so uncomfortable. They packed my nose solid tight with cotton and some sort of plastic to keep my septum straight while it healed. I was given pain medication but that was not my main issue because I wasn't in an enormous amount of pain, I was more just anxious and uncomfortable. I am usually a mouth breather but having your nose packed you begin to want to try and breath through your nose. Long story short I ended up pulling out the cotton on one side of my nose within 12 hours and had to go back to the doctor to make sure I didn't do too much damage. Luckily, he said I was going to be fine but wasn't happy with what I did :(
My suggestion if you ever have this surgery is make sure to ask for some Xanax along with the pain meds! My biggest issue was keeping calm.
