I got tagged the other day by my adult spider due to SFE. (Stupid Feeding Error) She got the webbing between thumb and finger pretty good, as well as the knuckle of that finger. The bite stung...the bruising on the knuckle afterward hurt for a couple days....but it's a really small sort of hurt. Not a big deal. It's the ITCHING after a bite that drives me nuts. LOL That can go on for several days.

I'll concur with others that the adrenaline rush from the strike is far more dramatic than the bite itself actually is. I've got two snakes that will furiously launch themselves out of their tubs on feeding day (the spider is one of them! LOL) and they always get my heart to racing.

Does that count as aerobic exercise?
