John is an Engineer. He and his wife Fiona traveled from far away to see Rowen. John had back pain, and he thought it was related to his hip. Rowen gives John an ozone injection to his SI joint. John says his back pain has disappeared. Rowen explains that the source of John’s back pain is actually the SI joint, not the hip. John says he is very logical, that he cannot explain how what Rowen did worked, but it worked. John thanks Rowen.
