Judy, I have a torn disc which has given me problems for eight years. When my pain was the worst, the only good position for me was standing. I had to work at finding a chair that I could sit in without pain. Even though my pain is much better now, I still drag my office chair around the house to sit in. I never, ever sit in a soft cushioned arm chair or recliner. At first, I could only sit on my exercise ball. You may need to experiment and find what works best for you.
Hope you feel better soon.
