The pain ran from my lower back to my right foot - and it was so awful my wife called an ambulance.
The paramedics gave me Valium as a muscle relaxant and the painkiller Tramadol.
This is when the discs, which act like shock absorbers in the spine, become flattened through wear and tear or start bulging out of their slot, irritating the surrounding nerves.
But when you look at the scans of the majority of these patients, there is nothing wrong with their discs - it'll be the mechanics of the back, particularly the sacroiliac joints at the base of the spine, that are more likely to be the cause.
It's when pain persists or increases after six months - or when it starts radiating down the leg - that doctors become concerned.
A slipped disc is often suspected in patients with unremitting lower back pain.
I couldn't bend over to put on my socks and I'd get huge spasms and fall to the floor, unable to move until a doctor came to give me Valium.
A couple of weeks ago I overdid things by putting up the Christmas tree and doing housework, and that night I felt I had put my back out.To see if it would work, I had to have pain-blocking injections of local anaesthetic and steroids.If this lessened the pain, I had a good chance of responding to radiofrequency.Many people have poor posture and when we do exercise, we'll often overdo it.Most people who get an episode of lower back pain recover with gentle exercise, anti-inflammatories and other therapies such as osteopathy, acupuncture and physiotherapy.
