I had 2 hernias following the daVinci procedure; the discomfort started a few weeks after sugery, and got progressively worse. Generally I would describe the pain as low in the abdomin first on the leftside which was repaired by surgical patch. Then 2 weeks after that a second hernia again low in the abdomin, but this time on the right side. A second surgery was required.
My symptoms were increasing pain when walking or standing with immediate relief upon lying down. The bulge in the abdominal wall was not all that apparent so I really didn't know I had a hernia at first. The second one (right inguenal) was obvious, and more severe. A week prior to having the surgery on the right side I could only walk 50 feet before being forced to lay down.
Hopefully you won't have to go through what I did, but if your pain persists your doctor will easily find the hernia if it's there. Good luck, and I hope you feel better soon.
