What can you do for a spider bite?

I had a spider bite last summer. Although I cleaned it thoroughly, it got very ugly looking. It was at the base of my index finger in the web...I likely gripped a handle and the spider was underneath.

The next day, it swelled and looked like several blisters, but they were hard. I went to the doctor and she told me there was NOTHING you can do for a spider bite except keep it clean. She said the toxin has already killed the skin.

It took a couple of weeks, but the blister-like swelling subsided and there is no scarring or other indication at the wound site.
