back pain office chair

I have severe back pain chairs true, but all different kinds. Any idea how to counter that?
I just back pain some chairs that I have to lie down for several minutes to let the pain go away. Obviously avoid those chairs would be the way forward, but many of them are office chairs I have to sit on a regular basis. Anyone had similar experience and figured out how to counter it? Thank you.
All I know about what to do is walk, I'm a truck driver and my back hurts if I do not walk for about 15 minutes every 5 hours. If you find a better way I know. Good luck
