osteoarthritis
"I found the reviews helpful,  In March I had a shot of Cortisone in my right knee.  It was effective for 5 months.  When my pain returned the doctor recommended Ortho Visc.  I had 3 treatments, each a week apart,  I had relief after a few days, but it didn't last.  I had the final injection on August 30th.  It really hurt, and I was light-headed afterwards, and could hardly walk.  The PA that gave me the last treatment had me rest until I felt OK to walk and drive.  He told me to mark 3 weeks on the calendar, at which time I  would feel no pain.  (Did that mean I would be dead?!)  After 8 days I am almost pain free!  Now to see how long it lasts."
