Dx - Osteoarthritis

5 years ago I had Euflexa shots in my knee and was pretty much pain free for all these years.......until about 2 weeks ago when, while on my daily walk, the pain returned. Oh no, not now! I have to walk all over Europe in a few weeks! So, today I went to the Orthopedist and got x-rayed........dx Arthritis! I need new Euflexa shots....but, no time before Europe for the series of shots.......so I got a cortisone shot.....ouch! Hopefully, the shot will work for a few months and, then, I will get Euflexa again. It is either that or knee replacement surgery......and, I want to keep all my original parts for as long as possible!
