I also had similar treatments by a trained Chiropractor and also by a similarly trained Physical Therapist. While those treatments helped some I didn't get much relief. I was going in weekly and the treatments were not as long and close together as what is described in the ".... clearpassage...." link above. I'd had 5 abdominal surgeries. The surgeon took care of them in the additional 2 surgeries I had for a total of 7 surgeries.
I say it is worth a try as that was what I was doing before the surgeries. (They wouldn't operate on me just because of the pain and occasional partial obstruction.)
Good luck! Please let us know how it goes.
