Post Malone had to cancel a concert booked for Saturday in Boston after going to the hospital again on Saturday due to what he described as breathing issues and stabbing pain on social media.

He visited the hospital for a second time in roughly a week. After falling into a hole on stage at the Enterprise Center in St. Louis last weekend, he received treatment for bruised ribs.

On Saturday, he tweeted, “On tour, I generally wake up around 4 p.m., and today I woke up to a cracking sound on the right side of my body.” “Last night, I felt fantastic, but today was completely different. Every time I breathe or move, it feels like a stabbing pain. I’m having a lot of trouble breathing.

He promised to postpone the performance.

I adore all of you so much. I’m really sorry, but I swear I’ll make things right with you. Austin Richard Post, who goes by the stage name Austin Richard Post, wrote, “I love you Boston, I’ll see you soon.

The play was “postponed due to unforeseen circumstances,” according to the venue, TD Garden, in a tweet. Tickets for the original performance on Saturday will be honored for the new date.

On Tuesday, Malone will perform in Cleveland.
