Spider Bite(s)?

At least that's what I think I've got. I'm not certain what type,
though, cause I never felt it and it doesn't hurt. There are two little
puncture spots maybe less than 1/8" apart.

I've been watching it because there is some bruising about 1" diameter
around the spot.

Another guy who takes aikido with me got spider bit on Monday and his
bite rapidly expanded and changed colors. He went to either a doctor or
the emergency room where they gave him some sort of pill that seemed to
have an immediate beneficial effect, perhaps steroids.

My theory is we both got bitten by a brown recluse, but it will likely
remain a mystery.
