Complete sham. You are paying them to see you for 2 mins to crack your back and say a bunch of stuff you won't understand about your back so you oblige. Had no relief in pain whatsoever. No diagnosis was done. I got better results from a foam roller and spine decompression. "Dr." Jay is not a real doctor and has not even been to medical school. I went to a real doctor who did actual imaging of my back and neck and determined I have a pinched nerve. Provided me with proper treatment that provided real relief and healing. Don't over pay for a back crack. Have a buddy do it.
