Don't take the Black Widow lightly....About 10 years ago, I was leaning on my bed to pick something up off the floor. Felt a little something on my forearm, brushed it off mushing it in to a squishy black ball of spider. As the day went on, I developed a cluster of blisters around the area where the spider was. Took some benadryl, and figured it was all good...heck, I'm a big guy, and the spider was little... As the day turned to night I could feel the venom creeping up my arm towards my chest. Very slowly. I'm thinking "it'll wear off". Now heading in to the early hours of the morning when I woke my wife up, and asked her to drive me to the emergency room. The venom had worked its way up my arm, and was starting to effect my chest.
Spent the rest of the night on IV muscle relaxers along with some other medical soup to calm the venom. They wouldn't give me the Black Widow anti-venom because the spider wasn't positively identified as a Widow, and the meds would have made it worse if they administered them.
Long story short, it took about 4 days after the spider bite to recover from it. I now kill Black Widows on the spot...
