The pop star is struggling to walk following a snakebite.
Mike Posner rose to fame all the way back in 2009 with his song 'Cooler Than Me'.
It was one of those absolute bangers that you couldn't go 30 minutes without hearing on the radio.
Since then he's had one or two other songs as big, including 'I took a pill in Ibiza', ensuring he could never given the dreaded "one-hit wonder" status.
Posner is currently taking part in a walk across the entirety of the United States, which has been cut short due to a serious snakebite.
Posner had crossed from Kansas into Colorado when he was bitten by a baby rattlesnake, which resulted in him being taken to a hospital.
He has shared a video of his rehab on Saturday evening, accompanied by the caption "Gonna rebuild with patience and equanimity."
From 24 miles per day to using this walker to get to bathroom. I’m on my way back. Gonna rebuild with patience and equanimity. pic.twitter.com/I2HYPmMO7L

"That venom is no joke!," Posner wrote in an Instagram post on Friday.
"I got to the hospital and got the anti-venom in time. Shout outs to G and Mike from the chopper team and Bo and Cassie and Whitney (my nurses)."
Posner set out on his walking journey from New Jersey back in April, with his plan being to walk 20 miles a day, reaching California next month.
