Sodium hyaluronate
osteoarthritis
"was told I needed knee replacement on right knee, not bone on bone yet but close. Had my first injection 12/13/16. Injection was not painful because it was injected slowly as it is thick, only felt pressure as it was almost done. Second injection was a horror as person injecting just slammed whole thing in and I was in severe pain could hardly walk out of office. I just had my 3rd injection yesterday and person who gave me first injection did it with no pain. I have felt no real pain in my knee since 1st injection so far. Dr said theres 6cc's of fluid that is now in joint so it may feel like your walking on a bubble. My issue is I'm having very bad back pain which I'm not sure if that is related to injection or not."
