osteoarthritis
"Originally I had SynviscOne injection 4/2016, & although it took about 6+ wks for my knees to feel full benefit, I was pain free about 4-5 months.  It was great!!  (Not everyone experiences the same benefit for the same amount of time, I was told.)   I started getting knee pain pretty badly again late Aug & by mid-Sept. I couldn't take the pain so I got steroid injections in both knees. My insur only allows 2 SynviscOne injections/yr.  By the end of Oct. the steroid injections had worn off so I got another SynviscOne injection each knee.  It's now 6+ weeks later (Dec. 10) & haven't had much relief to speak of.  I'm hopeful in next 10 days or so I'll feel more relief, but honestly it's the best med I've had for my knees."
