Knobbsworth, do you have Ankylosing Spondylitis? I don't really think you can cure the problem, but it may be relived through Physio or Osteopathy. Exercise can also help to improve flexibility of the fused joints, perhaps something like swimming, also checking your posture is good, a Physio can also help you with that.
MWB. I don't have any medical knowledge to say you have inflamed vertebrae discs, your problem may be as a result of Arthritis or something like Spondylitis.
It might even be something simple like poor posture or sleeping in a bad position. Many people, including myself suffer from back and neck pain, mine is primarily because of poor posture and until it is corrected, I will get little relief. I would imagine any inflammation is curable, once the problem causing it is resolved.
