Lower Back Pain: Please see a lower back specialist (e.g., orthopedic spine specialist or neurosurgeon) to rule out nerve impingement, bulging disc, degenerative disc disease of the lumbosacral spine, etc.

Disc problem: it sounds like a disk problem in your back is causing the issue. There are definitely things that can be done to help with this.
