Yes, my son tried this in July after spending three weeks weaning off of Lyrica. He tried three sessions, and he felt no pain relief at any of the sessions. Our first session was free, but the other sessions cost $250 each and were not covered by insurance. It made no sense to continue "trying" the Calmare therapy if it wasn't working at all. My son was the first patient on the new machine in Richmond, Virginia. The very kind trainer even tried some face timing to make sure that the electrodes were properly placed. It was a huge disappointment, that's for sure. Right now he is trying "creative" writing recommended by Dr. David Hanscom in his book Back in Control. He is on day 3, but he says that he has not yet noticed any pain relief. We are in week 3 of increasing the Lyrica dose back up. His pain levels have been elevated now for about the past 6 weeks, so for most of the summer. We knew that we had to try this during the summer. Thank you for asking. How is your husband doing?
