Daniel Marquis, 28, is battling a severe infection in his leg after unknowingly injecting himself with contaminated steroids. Mr Marquis, from Santa Clara in , underwent surgery in Colombia in a bid to save his leg but the procedure failed. Now the YouTuber has set up a GoFundMe page to pay for operations costing £23,562 (US$30,000), and remains in a Colombian hospital fighting for his life. Mr Marquis said: “I’m currently in the hospital and I’m in a really bad situation, and my leg is very hurt. I’m in the process of having surgeries. 

“I had one surgery that took all the money that I had and ended up being a failure and the stitches in my leg ripped open. 

“I have new necrotic dying flesh growing inside of me.

“I’m alone out here in Colombia, and I had a bad injection of dirty gear in my leg and it grew into a necrotic thing in my leg that’s spreading through me.”

Mr Marquis’ GoFundMe page has now raised a total of US$15,000 (£11,772).

The 28-year-old underwent a £7,854 (US$10,000) surgery three days ago, but the procedure failed after his stitches ripped open, causing the infection to spread even further.

He wrote on his GoFundMe page: “I am currently in the hospital alone in Colombia. I don’t have health insurance and 3 days ago I had surgery to remove the necrotic flesh that is spreading inside of my leg. 

“The surgery was a failure and also simultaneously bankrupted me. 

“The incision in my leg has burst open and there is now new necrotic dying flesh growing in my leg.”

“In this time of incredible physical and emotional suffering any donation no matter how small to help me to afford my upcoming surgeries to save my leg is something I will be eternally grateful for. 

“The first surgery was paid out of pocket and was in the area of 10 thousand dollars. 

“I have at least 2 more surgeries I need but do not have financial means to pay for them. These surgeries will also be more costly than the first. 

“Please help me, please share this on every social media you have. I have no where to turn.”

In December 2015, Mr Marquis moved from California to Bangkok in Thailand in hopes to pursue a career in bodybuilding.
