Sciatica and pain Dam Back .. Help

Years ago I had the same troubles and besides barely being able to get around I could hardly push the gas pedal in the car. I was sleeping on the floor and crawling around in the morning until I could stand up.
The doctors advised me I could have an operation but I would have to wear some kind of body brace for 6 months and there was still no guarantee that it would solve my problem. Technology might have changed by now, this was probably 15 to 20 years ago.
A woman at work had the same problems but had the operation and it didn't help her at all so I decided I would try to live without having any operation.
Someone else at work told me to get a book by the Back Doctor or maybe it was called the Back Doctor and after reading that book and following the exercises my back did get better but it took three years. It took patience and perseverance. Some of the exercises did hurt in the beginning but it got easier.
The book makes you think twice about how you are misusing your back and how bad our posture is.
I believe the book now has another updated version but I have never read that one.

Good luck
