Yes, I had a terrible experience but they all vary so I hesitate. My pain was on the inside of my knee and a little at the kneecap. The Iovera procedure was not bad as far as pain "getting" the treatment but the next day there were areas that I could not even touch, could not stand a sheet on it. The treatment did nothing for the pain area and it is hard to explain this but it numbed the wrong side of my knee (outer) and it is still numb but still painful to the touch. I know how that sounds, I question it myself. How can it be numb and painful at the same time. I had this procedure 6 months ago and am still numb/painful. It is only supposed to last 3 months. I cancelled my TKR surgery due to unrelated information I got 1 day after getting the Iovera and because of the pain, I had to go see the surgeon because the Dr. that gave me the Iovera was unavailable and I was told he had an emergency out of town. I have not seen him since. My surgeon told me that I should not have that when I reschedule my TKR but at this point I am very hesitant to reschedule. The glute exercises are getting me by. I am not pain free but manageable. I can't imagine fighting the Iovera pain at the same time as the recovery from TKR. I really hope you don't have this experience. Like I said, not everyone does. I have heard people say they were so thankful for it. The best I can say is it's a crapshoot. There is a group here that shares their experiences with Iovera.
