I have struggled with lower back pain for decades. I herniated a disk years ago and have degenerative disk disease. I tried an inversion table, it didn't really help and might have made things a little worse, I eventually sold it. I had an MRI and consulted a highly respected neural surgeon. He advised against surgery, said I was better off managing it with exercise and stretches. I think he was right, I am doing ok and it only really bothers me when I do a lot of bending as in gardening.
Consult a real doctor (not a chiropractic) and maybe a physical therapist. Good luck.
