alright here is my opinion, although probably not popular. There is the red spot then there is some erethethema coming of it. I would draw a circle with a marker around it to the very end of the redness till you see true normal skin tone. then go to bed. If it is farther then the marker, you need to go to the dr my lady, if not then it is slowly getting better, the body has it isolated, and can probably handle it on your own, and I would NOT drain it.
If you drain it you risk spreading the infection, seriously and that can be crazy bad.
If the redness is swelling the dr will do it, he will cut it, and debride it, as the organism is going to be in further tissue, then since it is probably staph he will leave it open and pack it while you take oral antibiotics.
Staph is a gram positive organism, and while I'm definatly not a dr, any drugs like penicillian, or amoxicillian, or better yet Augmentin will wipe that baby away.
If its getting bigger and you don't go to the dr you risk the redness expanding, where it is likely to enter the blood stream and cause fever, and sepsis.
Now of course this is worse case. Draw a circle and go from there.
I heard there is a site out there of free or low income clinics that might be your best bet. boils can be serious business.
