Fred;
The therapy did work, but only lasts for several months, unless you continue to do the exercises reguarly. Since then I have been taking {Glucosamine, chondroitin & MSM} pills, 3-5000 mg daily. I tried several brands and found one that works for me, I also bought an electrical stimulant machine, so when my back tightens up, I hook myself up and that helps too.
And I promised so many people I would not get old....oh well.
