osteoarthritis
"After having a few cortisone shots and not much luck or longevity with them,  my Dr asked me try the Synvisk 1and I was reluctant at first but when you have 100% bone on bone in one knee and 75% bone on bone in the other I was willing to try anything. I had to wait also to be approved by Wellness Blue Cross Blue Shield. It was finally approved and i had the shots in late July. I'm 49 yrs old and a bigger heavier man and I made my 15 yr old son come in to watch. It hurt like heck. My son was shocked to see me wincing in pain the entire time. It takes a little while to get it all in your knee as well. Then to my other knee I gripped the table and said my god nobody said they were this painful. Swelled up so bad for a week. Never helped me."
