What kind of bug bite is this? If’s extremely itchy and burns when I touch it

I posted this a few days ago but now I’m able to see the where the actual bite is, I live in Southern California idk if that matters or not. It was weird tho, because I was perfectly fine prior then I had to walk outside at night to grab something from the car, I didn’t feel anything in the next day when I woke up, I noticed when I was walking my foot was burning and really itchy so I don’t know if I got bit when I walked outside or if I got bit while sleeping but I want to know if anyone has an idea of what bug bite this possibly could be
