Query: Yamuna massage: dangerous and destructive

Perhaps there are constructive ways to engage in ball rolling massage; but a Yamuna massage therapist has left me with excruciating pain, pinched nerves, damaged muscles, my body out of line -- in a single, one and a half hour massage. As I explain my predicament (I was perfectly healthy 3 weeks ago; friends are puzzled that I can barely walk now), I've heard other stories, about the damage those balls, and techniques can do: a cracked rib, for instance. I'm furious at my experience; I think the whole idea is irresponsible, especially for self-medication. But further, I wouldn't trust a Yamuna therapist to be anything but a zealot, intent on "fixing" you. And that's not good for one's body. Watch out!
