I had sciatica and I have three bad lumbar vertebrae. I started having problems after a long road trip about 8 years ago. The pain would grow when I stood around or milled around for a while. Thankfully, I got out of shopping with my wife.
This problem went on for years. I found shots for pain management wouldn't do much or last very long. I don't suffer much from the sciatica lately, and I think maybe my stretching exercises helped. I do a lot of touching my toes, and bending side-to-side, etc.. Good luck with your pain, Mike. It's no fun.
