30 is young. Back pain is mostly a collection of chronic pain symptoms that don't correspond to meaningful harm or damage. You're probably not in need of "healing" because there's probably nothing actually wrong with you. You're not broken; you've just trained your nervous system to produce a pain sensation because you're hyper fixated on it.
I don't know why all these memes are coming up that contribute to this idea that being over 30 means you're somehow disabled. You're probably not, and perpetuating this idea is decidedly unhelpful, even in a joking context.
When I turned 30 I committed to taking fitness seriously. I reached a higher level of physical fitness and athleticism than my younger and less disciplined self could have managed. I was able to perform on an much higher level in my chosen occupation, which was performance based and exceptionally difficult physically, and because I did more strength training I had the ability to inoculate myself from injury. Basically, I feel better than ever because I started taking this stuff more seriously.
You have agency, too.
