I was bit on the ankle about 2 days ago, and I'm sure it was from a spider as we have a few roaming around in the house. I've never been bitten by a spider, so I'm not sure what my skin is supposed to look like. I think maybe it was stuck in my sock and was trying to get out, but I didn't notice it at all. It's itchy, swollen, leaking, and red. I'm not sure if it's infected, or if the spider was poisonous, or if this is just your typical spider bite. I don't want to go to the doctor only for them to say it's just a mosquito bite or something (They don't come out during winter anyway), and I'd like to avoid going to the doc altogether.

I don't know how to post multiple pics, so these are uploaded from tinypic.com. Here is the suspect: Tiny, brownish black with an interesting white design on the abdomen.

The abdomen looked more of a brown to me, but now I don't know since I killed it and threw it somewhere already :(
