Yesterday evening I noticed a small irritated area on my ankle with a white blister in the middle of it. I've had some mild hives recently and figured this was another little out break. However, the this morning the blister had swollen to the size of a dime and was sharply painful to the touch. After a great deal of internet research, I came upon some pictures of spider bites online, and there's no doubt my blister is a spider bite. Unfortunately, the pictures were mostly of a Brown Recluse Bite, which includes a venom causing necrosis (meaning it kills the skin). Apparently this gets pretty ugly and can take a long time to heal (google image search if you're curious, but not before a meal).
Anyway, now I'm all freaked out, of course. These spiders are rare where I live (Washington, DC), but anythings possible. I called the poison control help line, and the operator stated that a trip to ER isn't warranted unless conditions worsen. Does anybody have any experience with BRS bites or spider bites in general? Has anyone else had any nasty spider bites that sound similar but were BRS? How can I make confirm that is or isn't a BRS bite?
I took a couple pics, but I don't know how to use an image host. The blister is about the size of a nickle and is raised about a half inch, very tight with yellow liquid. No other coloration, red irritated area around it that went away with oral Benadryl.
