I'm not liking the run around I'm getting at my doctor/imaging location. I've had 2 orthovisc injections with 3rd one scheduled. What happens if I don't have the 3rd one? I'm getting skeptical that it is going to help & not wanting to go thru this for only a few months of relief. Seems I'm having better results with stretches & exercises. Have osteoarthritis in both knees & am having other issues with my other knee, so not sure at this point what to do
