My wife had the Iovera procedure done 3 weeks ago and is experiencing the same issues. It is painful to the touch, continuous pain, pain in the knee, weird nerve sensations. She saw the doctor today and he figured out the cause of the complications! Ultrasound revealed internal tract marks from 2 out of the 3 needle sites. For now she was prescribed Lyrica and will follow up in 6 weeks. The doctor thinks the nerves will heal but also stated he hasn't seen anything like this before. The freezing occurred throughout the whole needle and not just the tip the way it is supposed to work.
