Picked Right Nostril 2.5 Weeks Post Nose Surgery: Right Side of Nose Immediately Swelled

The swelling occured in the area where my nose is pinched. It also hurt when I touched it right after the swelling occured but doesnt hurt anymore. I think I removed a crust.It's almost been a week and it seems the swelling has not reduced much . What have i possibly done to my nose? Did I open an incision? OR will the swelling go away eventually? Thank you.
