Osteoarthritis
"I was experiencing knee pain and received a cortisone injection with fair results. Four weeks later I was offered and received  Monovisc. They told me not to expect improvement for 3-4 weeks. It&#039;s been six weeks. Since the day of the injection, my knee is worse. It is stiff, and gets stiffer if I sit for very long. I have to be careful about how I move it are it can have pain."
