A recent one I found: If you get a pain in your back that returns whenever you walk.. Take a trip to the wildest wilderness you can reach without needing to walk there, then start walking on uneven terrain. It is a huge difference on the muscles the body need. And just a forest path with a few roots isnt enough. Get off the path. Take the harder route. And be careful to not hurt yourself, of course.
My chiropractor made a small suggestion that a walk in the forest could help, and I discarded it because I was already "walking in the forest" a lot. Except I kept to the well-trodden paths. And I walked on asphalt to get to the forest. And it didnt really help. And the exercises he told me to do at home didnt really do much.
My current guy is all about not wanting to see me, and wishes for my continued success in doing so. When I do drop by, and I'm active, it's a checkup and a "keep doing that and now fuck off for 3 months" as part of long-term care for a life-altering slip-n-fall 30 years ago.
In fact, I've had like 6 chiros in my time, as we tend to move about a lot, and while their diagnostic gear changes from place to place, the hallmark of a good chiro is "do these exercises, stay mobile, and come back if you feel you need to; but I'll be happy if we only talk once a season".
When you first need a chiro, see two. Drop the one that seems to be too mercenary or woo-woo-crystals-magic.
If you're rough on your body, they can be an absolute godsend.
I'm at the point where I can't always get my skeleton to go back to where it ought to be, and a good chiro can find exactly which bones aren't.
Last one I went to was during a bicycle tour. The campsite wasn't ideal, and I awoke not being able to look left. Like at all. Turn to the right, ow that hurts, try to turn left, head stops straight forward, sharp spike of pain and no further movement.
Well whatever. Break camp, mount up, ride a couple miles. Now I'm warm and loose, right? Do some stretches. Go through as much of the routine as I can, get some pops and creaks, but still can't turn my fucking head. Slightly better.
Pedaling like this is a fucking bastard, because it's not just my neck, I'm all fucked up, but the road lies ahead and we go.
Get into town some hours later, have some lunch, a couple beers, still can't move for shit, see a sign for a chiro. Guy does walk-ins, thank god. Gets what we're doing, says 'well, I'm never gonna see you again, so I'll do the best I can in one go'
I think that motherfucker popped every goddamn vertebrae in the whole spine, and some of em twice.
Felt like a new man. Finally felt those beers. Rest of the tour went fine
Core strengthening can help with back pain, but in this case it's different. Walking on soft or variable surfaces causes less impact pain to sensitive nerves. People with poor flexibility or damaged discs in their back feel more pain from walking on hard, flat surfaces. The quality of shoe support / insoles can help with this too. If you have back pain when you walk, you start to compensate for it with an uneven gait, turning your pelvis inward or outward or tightening your hips. Over time this will cause tight muscles that will pull your spine out of alignment and exacerbate pain. Uneven terrain will force a break in these habits and encourage mobility and stretching in tight hips, hams and back muscles. This can be improved off a trail by doing mobility exercises like 3d lunge matrix, kinetic hip flexor and hamstring stretches. I would add that while you can prevent most back pain by doing core strengthening, wearing supportive footwear and doing these kinds of flexibility/mobility practices, it is always better for your body to have variability in how it exerts itself, than doing the same exercises over and over. Hiking is great for this because the terrain and the way you tackle it changes a lot each time you hike.
Oh yeah and a chiropractor will not resolve issues like this. Find a physical therapist that works with athletes and kinetic mobility/recovery stuff. Most PTs work with old people, post op, or chemo patients and are too gentle/slow in their approach to younger folks who need to retain their bodies.
