Went to the Dr. and found out it was staph and got good antibiotics right away before it spread too far. If the swelling and warm redness continue to grow, I would get it checked out. If it is an infection, you want to get it taken care of early. If it gets too bad, they will end up cutting it open and lay you up in the hospital for some time on IV antibiotics, and those aren't cheap. A friend of mine was just in for that and it was $2,500 a day just in antibiotics. If you have insurance, it may not be a big deal, but being in the hospital is no fun.
Keep a close eye on it and maybe even circle with a pen the area that is red and watch to see if it is getting bigger than the circle. If it is, I would definitely get it looked at.
Not trying to scare you, because there is a good possibility that it isn't anything, but it is much better to err on the side of caution.
