Post Malone had to cancel his Boston show an hour before he was set to go on stage, after he was hospitalized from his fall on stage last week.
He went to social media to reveal he was have trouble breathing and moving.
"Boston, I love y'all so fu**ing much. On tour, I usually wake up around 4 o'clock PM, and today I woke up to a cracking sounds on the right side of my body. I felt good last night, but today it felt so different than it has before. I'm having a very difficult time breathing, and there's like a stabbing pain whenever I breathe or move."
Hopefully, he gets better real soon!
