Can the suction from Velashape treatment cause a hernia?

I had Zerona treatments done, and after was given a free Velashape treatment where they roll a suction device with heat over my abdomen. Afterwards my belly button area looked different, the top had an overhang that wasn't there before. I just saw my doctor about it and was diagnosed with an umbilical hernia and now I have to have surgery! I have had 3 babies which is a risk factor, but I think it was the Velashape because the technician ran the device over my belly button area several times with suction.
