You should try a chiropractor. First of all, you can't see pinched nerves on an x-ray. You can see degeneration (everyone has it) and loss of disc height, poor posture, etc. But you don't see nerves or discs bc they're soft tissue.
A lot of chiropractors are salespeople. I hate a good portion of them honestly. And I am one
But if they set you up for a 24 visit treatment plan on day one, sell you supplements, offer you pre-pay discounts and the like then walk out. Find a good one, give them 2-3 visits/week for 2 weeks. If you're not feeling substantially better at that point, then you're barking up the wrong tree.
I usually tell my patients in a similar situation, give me 4 visits and if we're not making good progress or at complete resolution, let's talk about at least co-managing care with another provider. Next step if chiro doesn't work is MRI. That'll show any protrusion or extrusion of the disc. Once you know, other options are now available....pain management, surgery, etc. I will say I'm not a big advocate of lower back surgery, definitely not fusion.
Also, start stretching. If you go to a chiropractor, they should be giving you stretches. Most important muscles to stretch are the leg muscles, as they all attach to the pelvis, which is the foundation for your lumbar spine. Work on piriformis, hamstrings and hip flexors specifically. YouTube is a great source if you want to start that portion now.
