I am starting a thread on lower back pain that began off-topic in another thread. Here are the relevant posts to start. I don't know if supplements is the right category because the fix is unlikely to be a supplement.
I've tried several different mattresses, there's no mattress in existence that helps with lower back pain, no matter what they advertise.
If there were an aeron mattress like my aeron chair, maybe, but they don't seem to be making one of those.
I sleep on my side and back. While I'm asleep I have no control over that position, normally I wake up halfway between back and side and in pain, so getting back fully on my side with a pillow rammed up my crotch is the only way I can get rid of the pain, till I wake up again, pillow fallen out and me somewhere in between side and back. It's hopeless IMO, nobody can design a bed that covers all positions. I'd love an anti-gravity bed where you just sleep in a floating position.
I've tried literally *everything* people suggest *but* a water bed. My parents had one when I was a kid and I don't recall it being all that comfortable to sleep on. Probably the wrong thread to talk about lower back pain.
I exercise (HIIT) 4 times a week for 30 mins combined with full bodyweight calisthenics, I also use the sauna for 20 mins, sometimes twice back to back.
I do yoga style core building exercises after HIIT while stretching.
I have tried every mattress there is, I travel a lot too so I've been on a lot of different mattresses, none of which are any good. Sometimes I think I found one that works, but that only lasts a day.
The only thing that seems to relieve it for most of the day and sometimes even more days is hydrogen water combined with infrared light therapy. The problem with the "therabulb" I got at first is that it eventually, after three weeks or so, started to burn my skin no matter how far away I set it. So I got this pad with a bunch of 660nm and 830nm LEDs on it that does the same job so far I think. This is just treatment though, not cure and not a root cause (sleeping in a bed) fix.
That episode of Louis comes to mind where Louis CK goes to the doctor about his back pain and the doctor just tells him it's age, a loss of cartilage and collagen and the spine isn't designed well for upright walking. It was a funny episode but something along those lines.
On an further Off Topic side note, I cured 5 inoperable crushed (not yet fused) lumbar discs with just a week's worth of Ostarine SARM pills. I went from being unable to sit up in bed to lifting luggage without pain. I can't vouch for anyone else's results but this fortunately worked for me.
@DareDevil I've not tried Ostarine yet. I don't think that's my issue but who knows?
