G'day,
Yes I know what you are talking about. I have a similar but not identical problem, and it seemed to be initiated from overdoing lunges in the gym with a barbell.
I don't have a cure, nor do I even know what it is, but I have some theories.
1. Facet joint inflammation, caused by degeneration of the facet cartilage - a facet joint injection is a sure way to diagnose/treat this
2. One of the small muscle insertion points on the tran. process has been torn/severly damaged, and will not heal. If you look at an anatomy diagram, these muscles are extremely slender, and I propose that the slightest stress as they are trying to heal will damage them again, so that a cycle of inflammation, and scarring develops.
I know this isn't much but one thing I have found that relieves the pain somewhat is this.
Get a water running belt [ from an aquarobics store/site] and go to a local heated pool. Put the belt on and get in the deep end of the pool and just walk in the water for about 20 mins. I guess this is decompressing the spine and spinal muscles, and strengthening the supporting muscles without aggravating the damaged muscles.
Another help is to get a light compression back support brace and wear it while sitting. I have found with this I can now ride my motorcycle for 40-60 mins., whereas before I could barely ride 15mins without aggravation.n't.
I have found the following actions agggravate
1. Sitting
2. lunges/deadlift type exercises
3. Hip flexion extension exercises., with the knees straight
All I can do is just try and either stand or lie down most of the time, but if your job involves driving then it's not much help
Good luck
