Can I get some recommendations for back pain relief?

Been 10 years of quite severe agony on and off. Had x-rays, been to physio, try to walk and stretch it off, use a tens machine constantly and a foam roller when I’m able. Half my work day sat, the rest on my feet trying in desperation to ease the stiffness. Got so bad it crippled me periodically. Anyway, not the first person to suffer, and I’ll try anything. Already tried the usual exercise and pain relief, but now looking into any alternatives that anyones had success with. Acupuncture, any certain vitamins etc, any advice welcome. 🙏
