Just reading the updates and came across this. My experience with Iovera was not a wooden leg feeling. In fact, everything except my knee was numbed. The procedure itself was not that painful, it was and is what I am experiencing now. Burning pain, muscle pain, just generally painful where I expected it to be numb. I did not have the surgery due to another reason and I didn't know I wasn't having it until the day after Iovera treatment. So I am still suffering from the painful effects of the Iovera. I hear it works for some people, for me it would have just been a painful addition to the surgery. It is a chance people take but I would never do it again.
