It sounds like you could be suffering from a deteriorated disc in your lower back, and/or weakened pelvic muscles.
I too have a deteriorated disc in my lower back (birth defect from short leg syndrome) and I found that liquid glucosamine from Synflex (website online) has helped me tremendously.
It couldn't hurt to get X-rayed by a chiropractor and make sure you don't suffer from a shorter leg than the other.
As for the weakened pelvic muscles, there are various back exercises that a chiropractor can offer you, some work, some don't, just takes time to figure out which ones help.
Best of luck.
