I was experienced with MRT was when my wife caught her heel on the stars carpeting and fell down fracturing her tailbone one week before going down to Mexico on vacation. We did not think we were going to go as the only way she could sit was on an inflatable doughnut She had three magnetic applications and was like a new person. Plane trip was OK and when we had to evacuate the hotel and sleep on the airport because of Hurricane Ivan she had no problems. Great pain free vacation. everything was OK, we know it work
