osteoarthritis
"I had arthroscopic surgery in 2012 to clean up the damaged cartilage under kneecap so basically bone on bone under knee cap.  They also did lateral release to straighten kneecap.  Two months later I had series of 3 Synvisc shots which lasted two years.  I don't remember two much pain.  In 2014, I waited two long and until I had a lot of pain to get next series of Synvisc.   Last shot was painful.  We switched to Euflexxa and I just had second shot yesterday.   The pain the three days after is the worst.  After first shot, it took 3 days to recover and four days of no pain before second shot.  Today is day after second shot and I have much pain.  Will report back after 3rd shot and update to see if this is better than Synvisc."
