Don't take this as medical advice but here is some information that might help you decide on a course of treatment. Is the bite getting better? Many times if the bite gets better or symptoms start to subside after a day or so it's a good sign. Most allergic reactions will occur or at least start to occur relatively early on after the bite. If and that's a big IF, it is a Brown Recluse bite and be forewarned, I've only seen two, the center of the bite will ulcerate and give the appearance of a popped blister. Both of the ones I witnessed began with a white center about the size and consistency of a cigarette burn. Both turned dark in the center, almost black after a couple of days, and BOTH required substantial tissue removal to stop the damage. The thing to remember is that Brown recluse bites will not get better on their own. Early intervention is the best choice. Black widows release a toxin into the bite and while they don't tend to ulcerate (unless infected) they are quit painful and can cause neural problems sometimes lsting for weeks. I've never seen one that bad and we have a few every year where I work. Scorpions also fall into the bedtime monsters, at least around here. They just plain hurt, I did one of these years ago and thought I had stepped on a lit ciger when it happened.
Best advice, if you think it's getting worse, go see a doctor. If it turns out to be nothing, all you've lost is some time and a little money.
Good luck
