A nagging back injury is going to force Crowbar frontman Kirk Windstein to perform while sitting down during his band’s co-headlining U.S. tour with Eyehategod.

With tour dates kicking off tomorrow, Windstein took to social media to let fans know about his current health condition, the pain he’s experiencing, and his positive outlook on how he’s going to manage playing while dealing with severe back pain.

“Hey, this is Kirk Windstein from Crowbar here. [I’m] super excited for the upcoming Crowbar/Eyehategod co-headlining tour. It’s gonna be amazing.

“A little quick bit of info. I have sought medical attention both at the hospital and through my chiropractor, who I really love, and I either have, at the worst, a bad sciatica flare-up or potentially a ruptured disc in my lower spine. I don’t know either way, but, well, I don’t call in sick. I’m there to give y’all a hundred percent and please the fans the best I can. So I’m probably gonna have to start this tour, which begins Thursday in Orlando — a sold-out show, by the way; thank you all — I’m probably gonna start this tour sitting down, but we’ll be singing and playing top-notch the best I can do. I can’t walk right now, and that’s the truth. I’ve got a cane, I’ve got a walker, and I’ve never had this kind of pain in my life. I’m 60 years old, and I’ve never had this pain in my life. But anyway, I think positive; I don’t think negative. So it’s gonna be great, and we’re gonna kick ass every night. So thank y’all so much.

“Get your tickets. Shows are selling out quickly. And let’s go rock with Crowbar and Eyehategod and do this thing. Thank you all.”

As mentioned before, the tour with Eyehategod kicks off tomorrow in Orlando, Florida and runs until August 31 in Pensacola, Florida. Along the way, they’ll make stops in Atlanta, Boston, Chicago, and even the Rocks Off Concert Cruise in New York City.
