For me, they are related.
Treatment by an osteopath gives me temporary relief. Have you tried an osteopath or a chiropractor? You might want to do something about it, cause (in my case) lower back pain has the tendency to get worse whenever I don't see my osteopath to push and pull things right.
Are you sure you don't have a hernia? Or an affection of the sciatic nerve? That might also cause the lower back pain, and being uncomfortable sitting. Manual therapy or accupuncture might help you with this problem.
