I think it's just a part of aging but will throw it out any way. I'm tall so it's the lumbar area. I do back strengthening and while it helps a lot it doesn't make much difference getting outta bed or the lazy boy. Think I need to find a new bed and ditch the lazy. The reclining part is what might be contributing to it. It may make more sense to have a sturdy back rest with a separate leg rest. I've also figured out the best time to do stretching is right after I get out of the shower. That way it gets done. I do have a lumbar cushion for the lazy boy. Helps a ton, but I fall asleep in it and that's the big problem. I'm thinking maybe a small soft pillow and sleeping on my back. Any thoughts is appreciated.
You probably know the saying "Never lift and turn"? I lifted and turned when I worked at a lumber yard and have had intermittent problems since then, which was 1975. If I'm active and getting some kind of workout, it's fine but if I do the long-term couch spud thing, it can go South pretty fast.
I have tried many things- back bridges (laying face down) to tense and relax the muscles, stretching, Alleve (that stuff is great!) and just being careful. While these all work, I found that the foam roller from Wally World gets it back in alignment faster than anything. I don't go to chiropractors and it's usually a matter of twisting one way without going the other, to balance it. If it goes out, I need to relax it enough to turn the opposite direction and when it goes back, it makes a slight click and I'm fine.
