For awhile, I have had knees that tell me when it is going to rain. Last week, I limped around the campground when we camped with friends. I had an MRI last week, and was told I have little to no cartilidge in my right knee. I had a good amount of fluid removed from me knee and had a cortisone injection with good relief. The MD suggested that I get a synvisc injection. Anyone had a similar experience?
