Hi there! I too have suffered with osteoarthritis for many many years and just put up with the pain. Recently, my right knee was so painful. It became black and blue when I walked for too long. I have bone on bone arthritis. I had a Cortizone shot which was unsuccessful. Last week I started with the hydroponic acid gel injections. The doctor said the first and second won’t work, but by the third, I will start to feel relief and I could have a fourth many people do well with this, and I am hopeful One friend had no success with it. The other friend has been fine for two years. I am praying that I have success but next will be a knee replacement which I dread.
