I’ll check that out. I have lower lumbar DDD and found that exercise and stretching are also essential in reducing leg pain/tension and various sciatica’s. One tool I use are a variety of foam rollers including the curved Rollga soft, and the OPTP brand soft and extra soft rollers on my legs all over every day as part of my exercises. These rollers relieve a lot of tension and sciatica pain for me. All are available on Amazon.
