He also makes occasional appearances on the independent circuit. He is also well known for his tenure with WWE, where he performed under the ring name Dean Ambrose from 2011 to 2019. Speaking with PWInsider, he explained how he’s feeling after leaving WWE: “Good actually.
I’ve had a obviously some time off like everybody has recently. And had time kind of to slowly over time rehab various injuries. My lower back have screwed up for a really long time. I had, what do you call it, a pinched nerve in my neck between my C6 and 7.
It was making my left arm go numb, and that was really horrible and painful, and so forth. And obviously I had all this mess with my elbow that hopefully is over forever nowBut all in all, pretty good. I was able to kind of after leaving WWE kind of figure out the things that were wrong and kind of fix them over time.
And I had time to do that and to train properly and rehab things properly and stuff. Because really for me, what ran my body down in the grounds over time was the travel, because it’s that and getting put there two tables on house shows five nights a week for years straight.
But it’s like, I go through the table, but then you got to jump in a car and drive 300 miles, or get on a plane, or get on a charter, or do this. And I went so hard for so long, and wrestled so many matches so consistently.
And once I had gone a couple of years straight without missing a day, and everybody else at one point had been hurt, or had taken a vacation or whatever, and I realized kind of the mark I was getting for consistency and kind of being the iron man, then I kind of started to take pride in that. I was like, oh, okay."
