Jon Gosselin woke up in “excruciating pain” after he was bitten by a venomous brown recluse spider while sleeping.

The “Jon & Kate Plus 8” alum was at home in Reading, Pa. when he was bitten by the dangerous arachnid and rushed himself to the hospital.

Gosselin, 44, told The Sun that his leg ballooned to twice its size and he limped to his car to quickly seek out medical attention.

“I was DJ-ing for the weekend in Philadelphia and I finally felt free,” the recently single reality star told the outlet.

“It was my first real single weekend. I was totally ready to open up and meet new people and start fresh. But I woke after a night of music and fun and went to stand up only to fall back down on the bed. I was in excruciating pain.”

Although Gosselin didn’t know it at the time, brown recluse bites can cause loss of limb or even death if not tended to quickly.

“My first thought was ‘What now?’ I have had a rough year, my breakup was hard, then I got COVID, which was bad,” he added. “It was really weird because when I looked at my leg I realized it was twice the [normal] size and there’s a red-looking blister with a large red circle around it.” 

Gosselin continued, “It kind of looked like a cigarette burn, but really raised. The doc immediately knew the pain was from a brown recluse, which is a deadly spider. My entire leg had swollen up from the cellulitis.”

The father of eight, who is currently on a road trip with his daughter Hannah, 17, said he had to call an exterminator to ensure the creepy crawly was gone.

“The doctor told me that I was lucky to come in because if you don’t treat this you can lose limbs or die from a bacterial infection. I just wish I knew where the spider was so I can take my revenge.”

He added, “I went through days of severe pain and now the antibiotic is so strong it’s made me ill. I’m losing pounds again.”

It certainly hasn’t been the best year for the former TLC reality star. He was hospitalized in January with a severe case of COVID-19, before calling it quits with long-time partner Colleen Conrad, 51, amid her cancer battle.

Gosselin’s rep did not immediately return Page Six’s request for comment.
