Thank you for responding, Shelby. When I finish off the bottle of Osteo Bi-Flex I now have, I will get the formulation with hyaluronic acid in it. I tried to look at the link you posted for a NUCCA chiropractor but got a message saying basically that there was no such webpage. :-( While I am willing to try a chiropractor and my health plan says it will pay for it, I still have to hope that my primary care physician approves it. Thanks, again!
