L4 L5 degenerative discs. Many years.

Degenerative discs L4 L5, mild postero central disc protrusions at L4 L5 disc level indenting underlying thecal sac. Minimal anterolisthesis of L4 over L5 vertebral body is also seen. This is the verbatim advice by radiologist & Ortho MS Dr who suggested MRI. It was detected in 2016, but little back pain was from 15 yrs back. After allopathy, homeopathic medicine i am taking since 9 months -R11,R29, Sciatane, Reumatone as suggested by a homeopath dr. Physioyherapy is also being taken -TENS, Ultrasound, Traction, hotpack since 2 years, however when pain subsided we stopped. But now pain has resumed so physiotherapy is resumed now. Apart from this I also have Diabetes for which i am taking Glimisave M1, & High BP for which medicine taken is Telcros 40. Light walking i am doing to reduce weight n for exercise. Please suggest some permanent measure as pain had been for many years.
