Man Found an Odd Mark on His Body. When It Grew, He Went to the Doctor & Got an Unnerving Diagnosis.

Sup Travellers?! Prepare yourself because your blood is about to crawl. 

According to reports from the Independent UK, an Australian man named Dylan Thomas received an unnerving diagnosis last week after going to the doctor following the discovery of a strange mark on his stomach.

The 21-year-old found the scar while he was on vacation in Bali. He woke up to find a bizarre red mark on his stomach. When it grew a few inches, the 21-year-old went to the Bali International Medical Center.

After some investigating, Thomas said the doctors finally solved the mystery: a spider had burrowed itself inside his body through an appendix scar and had been living under his skin for three days.

"Well after running tests and putting things inside my stomach they finally found out it was a tropical spider that’s been living inside of me for the last 3 days, managed to get it out luckily," he wrote on Facebook. "Haven’t felt so violated in my life before! Just glad it’s all over."

Thomas said that doctors removed the spider by making a small incision in his skin and pulling it out.

Thomas has since returned to his home in Western Australian. He told local media NT News: "It was bigger than the size of a match-head."

Spider bites are bad but the whole situation of a spider crawling up into your body and burrowing its way up to your chest is just unnerving. And what's even more unnerving is the fact that the spider was alive the whole time. Anyway, my name is Trinikid and you've just been informed.
