Does Showereing in Hot Water Affect Your Nose?

I realized that when I go out of a hot shower,my nose swells up and goes really red,then it goes back to normal after a few hours,why does this happenCan the effect that showering has on my nose cause it to change size/shape?it never used to be,it was small and defined but since i was13 (16 now) it drastically changed its big ,wide and the nasal bone is not really visible apart from at the top even though I have bump from the side (which should mean it should be defined) but its flat .
