Okay, back from the doctor. Still no results from the culture. They will call me later in the week when they know something. Otherwise, the abscess is about 1/3 the size it was on Friday, and I am not in pain any longer.
Alright, so I finally have an answer. It is indeed a staph infection - and I been prescribed the proper antibiotics. Also, the abscess is almost completely gone, now - so I can sit comfortably.
