Advertisement Don't get bitten by this species. The actual bite didn't hurt that badly, but the venom caused my hand to swell up within a few minutes. My hand hurt like hell...so much so tht it was at least three hours before I could even fall asleep, with a sensation that felt like venom was "crawling" from the finger that was bitten into the hand. This pain was mostly gone by noon of the next day. Shortly afterwards, though, I started getting muscle cramps over my entire body. These cramps were worst at about 36-48 hours after being bitten, and lasted for more than a week. Overall, the cramps were more inconvenient than painful, but I would have to say that they're worse than the initial pain of being bitten. At worst, when my chest started to cramp up, it felt as if I was being stabbed by a knife (not that I know what it feels like to be stabbed in the chest by a knife, but I'm assuming it hurts a lot). Anyway, After about 48 hours, the muscle cramps got less severe. I'm actually still getting them, but they aren't anything to write home about. Interestingly, within the last 12 hours, the finger that was bitten started to itch and swell up again. Part of me thinks that the itching and swelling has something to do with the bite because, well, it's the same finger that was bitten. But then again, it's been more than a week since I was bitten, and I don't see why I would suddenly be getting new bite symptoms in the hand that was bitten. Who knows? Maybe I have a fungal infection. Or maybe I recently got bitten by fire ants and don't remember being bitten. Anyway, the fact that I'm feeling ANY effects more than 8 days after being bitten shows that this isn't a species to screw around with. And it was only about 3" max. I would certainly hate to get bitten by a fully grown specimen. A warning to newbies: don't get bitten by a P. murinus; especially a large one. It isn't a particularly fun ordeal.
