Osteoarthritis
"I got this shot on march 17 2016,it was a preventative measure because my knee is bone on bone and I would get a cortizone shot every 6 months.24 hrs after the shot, my knee swelled up and the pain was incredible and I could&#039;nt  walk. 3 weeks later after having my knee drained and injected with medicine I had emergency surgery to flush out the synvisc. I&#039;ve been out of work now for 6 weeks and with going to therapy am starting to walk a little better, I hope to return to work in 2 weeks.I had arthroscopic surgery 10 years ago on my other knee and the day after surgery I was much better than I am 6 weeks later after a preventive shot. be careful I think they are hiding all the bad reactions to synvisc"
