Could this runny nose be from the oxygen during my procedure (see details)?

I had (basically) a colonoscopy today under anesthesia, not intubated or anything but did have an oxygen tube with little nubbies up my nose. Ever since the procedure my nose on the right side has been horribly irritated feeling and has been producing a lot of snot, making it feel like I’m getting a head-cold. I sort of feel like it’s just irritation/dryness from the procedure and not a cold, but I’ve never had irritation so severe from oxygen before. I’m also sneezing a ton.
