Does anyone know what this is??

Okay so I’ve been struggling with a weird skin patch on my wrist and arms for about three months and it looks like this.

I have to go to the Dermatologist on November 28th, and they’re going to take a biopsy to see what it is. It flares up and dies down at least once a day. The next picture is on my hip, and I have no idea what the hell it is.

It doesn’t hurt at all. I didn’t notice it until I was getting into the shower. I thought it was a zit, but I tried to pop it, which I know is a bad idea. But nothing comes out. It’s just there with that perfect circle next to it. Are there any guesses as to wtf either of these are?! My regular doctor also asked if anyone in my family had lupus? But I don’t think anyone does. Any ideas?? Thanks!
