If you get further information on detrimental effects please advise

My pain after the injections is also worse. I have no idea why or what to do about it.

I also had the treatment with TKR, and experienced terrible nerve pain and knife like pain following the procedure. I went back to my surgeon, who approved the block procedure but was not the doc that administered it. My surgeon prescribed a steroid treatment after explaining it was neuritis, inflamed nerves as a result of the block. It helped immensely, but as soon as I completed the coarse of steroids, it returned, although not as intense. I’ve since had a second course with same response. I am 4 months out and have exchanged one pain pre op, to this knife like pain post op. I would never have done this had I been advised of this possibility and I did not find anything about this side effect when I did my research. My surgeon feels it will improve as the block wears off and the healing is complete that could take up to 12 months. I am still experiencing a vice grip numbing sensation mixed with knife like pain through out my knee with movement. I would never do this again and praying it will resolve.

I had the Iovera over a year ago before my knee replacement. I have never regained the muscle use at the injection sight. I to feel pain and the muscle feels dead above the knee where the surgeon did the injections. I am 55 and very active, not overweight. My surgeon gave up on me and sent me to a revision specialist for follow-up after I questioned the horrible stabbing pain and skin irritation. It has now taken me months to get an appointment. I only wish I could take that day back and had never gotten it. I went post op from my knee replacement with zero pain meds because he said I did not need them due to receiving the Iovera. Was the worst surgery of my life, and I will never trust another surgeon.
