possible staph infection?

samantha

does this look like a staph infection? it started out as just an itchy place that i assumed was a bug bite. then i noticed a raised head, making me think it was a pimple, and i was able to get a bit of pus out of it. but since, it is painful to try and pop it, and painful to the touch. it gets even more red and feels kinda hard if i try to mess with it.
