Luckily there are plenty of options on the NHS if people don't wish to pay thousands of pounds to a private clinic. I had amazing results from a free NHS inpatient programme run by the Pain Clinic at my hospital - I spent three weeks doing intensive physio and hydrotherapy amongst other things. An advantage of this was that I was checked by a qualified spinal surgeon rather than just by the physiotherapists.

If anyone is in a lot of pain I can really recommend getting referred to a Pain Clinic in the first instance, and take it from there. They are run by doctors who are specialised in pain management and have more options for pain relief than the GPs can offer.
