PORT CHARLOTTE, Fla.- A Port Charlotte man only talked with WINK News after surviving a poisonous snake attack on Saturday night. 

Frank Costello is still in the hospital, but is doing much better after a poisonous monocled cobra attacked and bit his hand, which sent him to the hospital. It caused him so much pain, he couldn't even sleep, but he's getting better every day after taking antivenin, and he should be going home Tuesday.

Costello said, "Thank God this was not life-threatening. It's not even close to that. Yeah, I made a stupid mistake, but I'm doing much better." 

Costello said he was cleaning the snakes' cage at Ridgeway Exotics in Port Charlotte and was trying to take a picture of the snake to put on Facebook to show people there's nothing to be afraid of.

Costello said, "I stepped over the line this time. I knew she was in a cranky mood and I pushed my limits with her."

He cleaned the wound, then disinfected it with vinegar and baking soda, and waited 45 minutes.

"My hand tripled in size. It was a little bigger then a beach ball. It looked like one giant hand, instead of individual fingers, and that's when I said this is a lot more serious then I thought," said Costello.

It was serious enough for Costello to go to Peace River Medical Center where he said he received four vials of antivenin from the Miami-Dade Fire Rescue. That helped reduce the swelling in his hand by 25 percent, and he expects to go home on Tuesday.

The Fish and Wildlife Conservation Commission said that it's standard operating procedure to conduct an investigation into cases like this to make sure there weren't any violations involved.
