Hard/tiny red lump on my back

Hello,

Directly in the middle of my back there's a very tiny red lump (about the size of a tiny screw on a pair of seeing glasses)

It's been there and hasn't gotten bigger for over a year and it sometimes itches (rarely) in the time I've felt it I always assumed it was a freckle I irritated when I scratched my back too hard one day, but after checking in the mirror I noticed it was red

Basic symptoms: bright red, no bleeding, no pain, no redness around the area, it doesn't itch constantly (in fact I barely noticed it till now), it's basically just a hard red dot on my back.

Any ideas?

Thanks
