Nasal congestion on the 13th day after surgery

After removing the silicone sheet on the 7th day, it's not like before the surgery, but I can still breathe through my nose. Is it really this uncomfortable? It's the 13th day and I still can't breathe through my nose. Do I feel stuffy? My left nostril gets better rest and the right nostril has less air than the left. Is it still because of the swelling? Will it get better over time?

Also, I don't have a runny nose, but there is a little bit, so I keep sniffling. There is also a little bit of snot on the roof of my nose. I remove it with a cotton swab before applying Fucidin, but is this also a normal phenomenon? The hospital said that you may have a runny nose after surgery.
