*Possible TMI* Boil or bug bite?

Preface: I have both psoriasis and eczema, and have been prone to boils in the last 8 months. Fairly certain this is just another boil, but I’d like some other input while I wait to see my doctor in a couple days.

There’s only one hole, which leads me to rule out bug bite. It’s drained a little already, green pus and a little blood (again, makes me think that it’s a boil. The red “ring” around the bump has gotten smaller, and the area is a little warm. This leads me to think it’s an infected follicle that turned into an abscess (boil). The last time I had a boil, my doctor looked at it and said it didn’t look like a staph infection, and didn’t treat me for one. I’m kinda thinking that it was, and because it was never properly treated, I’m still experiencing complications.
