I was scheduled to have my LTKR on May 2,2023 and i got iovera injection on April 14th 2023. In about a week, i had unbearable pain in my left leg with spiders crawling or pins and needles like pain all over the leg that kept me awake for three nights so i cancelled my surgery. The pain subsided in about a month or two but numbness lasted almost for 8 months. Recently, i did Robot assisted LTKR at Mayo without iovera and i am much pleased with the surgery outcome and recovery.
