John Barrowman had emergency dental surgery on Wednesday (18.11.20)

He wrote: "I had an emergency with my bloody mouth yesterday (again).

"Emergency abscess removed. All between 3ish and 6pm. Lots of panic and stress on my end and it was just a bit of a s*** day. Jb (sic)"

Before adding in a lengthier video to explain in more detail on his social media account, he said: "So yesterday was a bit of a day. Everything was fine until about three in the afternoon when I experienced pain in my jaw here. I went to the dentist and got it x-rayed and immediately, they sent me to the oral surgeon and I was put in a chair and they did a big root canal dig out on one of my teeth. I was there until about six o'clock in the evening.

"I kind of lost track of everything. My blood pressure spiked because of it and I got that checked ... I feel very woozy today and I'm a little bit sore."

Back in 2017, John had his appendix removed in emergency surgery.

He said at the time about his operation: "I feel like I have been hit by a car. I’m just sore all over and my voice is sore because of the tube going down my throat.

"The staff in the surgery knew who I was, they were fans which was kind of funny. I was just lucky my appendix didn’t burst, they caught it in time. I was in a lot of agony yesterday. I knew something was up, I felt really bad."
