After having the iovera treatment in my right knee, my pain has gone from about an 8 or a 9 prior to treatment to zero. I am now able to get back in the garden to pick beans, I can cut my grass again, and I am back to doing housework. Dr. Darr and his staff are great, they have become like family to me. To someone looking for a doctor. Dr. Darr and his staff are superb, he is truly top-notch.
