Yeah, blow your nose into your hands, then use the shower to wash anything that comes out directly down the drain hole. Gross idea, but cleaner in the end than using dry paper - and the OP has already confessed to rooting around up there with fingers, so I figured it was appropriate.
And a q-tip, don’t forget the q-tip.
Anyway, for days I could envision something small and foreign up there, but luckily it just went away.
That could seriously be used as a cheap and effective torture device.
Years ago a cousin of mine had to be taken to the hospital to have a dried bean extracted from his nose. It had reached the sinus cavity and wouldn’t come out. Doctor told him the bean could have sprouted if it had stayed up there long enough.
“He am Groot”? 
It could simply be nose hair. I found that, as you age, nose hair tends to grow thicker, longer, curlier, and in odd angles. Sometimes they bend and get stuck deep inside your nose. Finding and pulling such a fucker usually alleviates the discomfort.
Setting the scene for:
“Honey…? Why is there a needle-nosed pliers jammed up your nose…?”
“I’ll tell you in a minute… I’ve almost… got it…” :smack:
Could be your wedding ring…
