Insect/Ant bites

Hola
A few years ago I was bitten by what I think was a spider. There were two small holes in my elbow
No itch, only swelling . Went to the Doctor, who happened to be my landlord, he drained it, had me do a blood test and gave some drugs to take. The amazing thing was that his office was upstairs from the pharmacy (next to The Fishing Hole) and across the street from the blood testing lab. He made me better. It wasn't very expensive.
