Sorry for the graphic image, I've let this go for about a week. I've been meaning to get it checked out, but the student health center is closed on the weekends. I think I got this while sleeping.

 I live in Washington, DC so I dont know if it's a Brown Recluse (Wikipedia didn't mention anything about Brown Recluse spiders attacking in DC, but who knows).

Just recently today I put some neosporin on it, and it basically erupted in puss and blood. It has been doing so all day until I put a small piece of tissue over it (hey it works with shaving).

Are there any treatments I can use to hold me over until I see a doctor?
