Is there a person who I could pay that works in a lab as a profession that could examine a substance for me?

Background story (warning it’s gross and possibly NSFW)

I was blowing my nose and felt something unusual coming out of it. It seems like a piece of paper or styrofoam flew in my nose at one point. I WANT to be wrong, but I want a professional to examine said substance. I put it in a zip lock bag and hid it somewhere in my room.

Also, before anyone asks, no I did not snort anything.
