I use what most have tried before but in liquid form,,,, It's called glucosamine with condroidin made by Wellesse.... I get it in a quart size bottle at Sams for around $18 and mix a cap full with water once or twice a day... Within a few days every pain in my body goes away. I was an auto mechanic for some thirty years with a lot of back troubles,,,, this has saved me from any major back operations and keeps my knees and joints pain free! I actually was told about it by a fe doctors years ago and they told me it was much more effective if n used the liquid formula instead of trying pills and it worked,,,
