he was experiencing a "searing sensation" as a spider that had made its way into his abdomen through an old appendix scar, crawled underneath his skin, all the way up to his sternum.
Mr Thomas said he believed the spider had burrowed into his abdomen on Friday night as he noticed a mark on his stomach on Saturday morning that continued to worsen.
Mr Thomas spent another day with the arachnid tunneling inside of him, before going to a hospital.
"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,"
The spider was eventually removed with tweezers. It was dead when pulled out.
Mr Thomas said the experience had ruined his first trip to Bali.
