Welcome!
Alastair lives in the UK and is keenly tapped into the best surgeons (e.g. Dr. Lam). I hope that you have had an MRI at least. Many people here are very cautious about getting adjusted or having traction by a chiropractor if there are underlying spinal conditions.
A. w/find you or you can send him a PM. He's helpful.
If you have had an MRI, it'd be helpful if you put relevant information (also from flexion x-rays or a discogram) in your signature so people can more definitively see what's up).
You're at the right place and good luck. ~ ans
