I was a little hesitant at first as it was a lot of money for me to pay over what the insurance covered and I am retired disabled and very low on cash to go around, however, it was so painful to walk and my back was worse than my knee, so I HAD to try this🤷♀️ WELL, I was SO PLEASED!!! I was hoping for the full 6 months he promised but was so pleased that even after a YEAR I was still PAIN FREE!! I had another fall on my RIGHT KNEE which did horrible damage and cost dearly to my left Kerr in strain😭. It held up for a while more but now it’s bad again and I’m going to have another injection or this time my knee replaced😭😱🤷♀️🤦🏻♀️🤧
