I do have disc space narrowing at L5/S1, plus few herniated discs.
I have had a freeway motorcycle accident back in 2007. Broke 2 bones in my vertebrae (neck), got the brake handle in my thigh... I was 6 months in a "halo". Did some physical therapy sessions which did not help much. After 11 months of total recovery returned back to work in 2008. Now, for over 3 years I have been suffering with lumbar spine, lowback, sciatica, hip and leg pain. I do sleep 2-3 hours per night. Regular massages do help. I do have Vitamin D insufficiency and take vitamin D3 (2000 UI/per day). This past weekend spend 15 minutes each morning getting real vitamind D (sunlight) on my back lying on my belly. It seems to help. I have also started a "The Five Tibetan Rites _ Energy Rejuvenation Exercises" (look fot that video on youtube). Yet waiting for HMO approval to see an orthopedist.
I have the same/similar problem. Mine stems from running and training for Marathons. I found a few things which have helped with the pain, but not eliminated it. To eliminate it I would probably have to stop running completely (in fact I did this for 2 months and the pain declined about 90% slowly but surely).
I take Magnesium and Calcium pills every few days, plus viatmin D. I also reduced my running and replaced it with swimming. I also used to always sleep on my right side - I notice when I sleep on my back or left side, there is a noticeable improvement the next day.
Good luck.
The solution is to do various forms of crunch situps.
By strengthening my stomache muscles, it helps to share the load off of the back. Several months later now, my back is quite good.
I'm hoping you are doing well!! I have the same problem .
