@lindielulu - My surgery is scheduled for November 20 - I have been doing SO many butt exercises to prepare, and my surgeon (as well as the surgeon before him) have stated that I don't have that much damage in my knee (I tore my meniscus 3 years ago and developed OA in the kneecap) to 'warrant' such a brutal surgery. The pain is in my inner knee and the pain is only when I walk...it was controlled with cortisone shots, and they quit working about 5 months ago. I am also losing weight (want to lose about another 15 pounds to get to my 'ideal' weight before then) and I walk daily. The only thing that has me able to do this surgery is if I do Iovera because, honestly, when I had my double spinal fusion in 2009, NOTHING worked to take away my pain. The pain was excruciating and after Dilaudid in heavy doses was finally given, I started to get some relief...I still have a pain specialist, and he can prescribe that..but I just want the area numbed for as long as possible instead since I have such a high tolerance of pain medication.. I keep telling myself that the doctor who is doing the Iovera has been doing it for many years and have to try to trust he won't damage anything...
