Can someone help me figure out what this rash is?

Can someone help me figure out what this rash is?

Obviously I know to go to the doctor to get it checked out, and I will, but I don’t have enough money for a copay right now.
Anyways, I got this kind of a while ago, and I thought it was just from my dog. She’s a pit, and sometimes her short hair rubs against me the wrong way and gives me little bumps kind of like this,, and same thing with my grandmas frenchie.
Well, I’ve noticed that it hasn’t gone away in like a really long time, so I’m just wondering if someone had any idea what it could be. It’s kind of itchy sometimes but not to the point of being a distraction from anything. I got it months ago I think? It was a lot smaller when I first got it. I don’t have it anywhere else besides my arm, but it seems to be spreading down a little bit.

First ever oil painting!

My first ever oil painting!! I painted a picture of my bfs mom’s cat, for her birthday. I used to only paint with acrylics, but all my paints got lost or opened during my recent move so I decided I’d try this.
