John, I have a degenerative back condition( facet joint syndrome) and did try Glucosamine.......didn't find it helped all that much. I don't know what you do for a living but beware the Office Chair.......them wee beasties , if set up badly, can do an awful lot of damage.Get a work station assessment from your company, if appropriate, don't sit for long periods of time,take gentle exercise although swimming is one you should be a little careful of if you tend to do breast stroke as that arches your back in an unnatural way ( well, it does mine, anyway).
