Slightly crooked nose that comes and goes - what am I experiencing? (photos)

I had rhinoplasty done 7-8 years ago. I had a slight dorsal hump, deviated septum, and a slightly downturned nose. I noticed asymmetry to my nose and brought it up to my surgeon. It went unresolved. I'm not sure what the issue is because sometimes when its cold or i have a runny nose my nose looks perfect but then it swells up again. I also feel hardness on the right side of my nose. What am i experiencing?
