I was in severe pain for about 6 months. During the acute phase, I went to physio and massage weekly as well as spent lots of time stretching. That was about 8 years ago and I still stretch, make sure my core strength is good and generally pay lots of attention to the health of my back.
I swear by my physiotherapist and info from a New Zealand phsyio called Robin McKenzie.
I researched the surgery option and learned that several years after surgery, people who had surgery and people who didn't were pretty much equally healthy.
