Some say they're life savers and others that it's all hokum.
A good Osteopath is a godsend! Mine (a BUPA one but paid for by the NHS for 6 months) got me back on my feet again. She gave me exercises to keep me mobile, and the right stretches to do to ease it when pain returns (it often does if you turn awkwardly, once you've damaged a bit of your spine
) I also got posture advice to help straighten the deep curve in my lower back which wasn't helping.
This was after 4 months treatment by a physiotherapist in the Osteopathy Dept at the local hospital which was next to useless
So good luck - hope you find a good'un
