Hi. I'm just wondering how old you are?? Sorry - didn't read your previous post. Your symptoms could be from ligaments or disc. A lot of people have degenerative changes in their spine but this isn't necessarily the cause of pain!! Your age and the history of how you injured your back would indicate how to manage things from here......have you looked in to the McKenzie approach to low back pain. Some good stuff here if you can locate info online. I'd google "the McKenzie Institute" and have a read.
