CoolSculpting on belly 20 years after hernia removal in groin

Female aged, 29, stubborn fat on belly. Considering cool sculpting, however, in general contraindicated for adjacent hernia. Original hernia was removed at age 5. About five years ago, I felt a little pea lump b/w right leg and groin mid way down. I had a scan to see it was still visible in adulthood and it is there about the size of a 10c coin. Surgeon said nothing to worry about unless I want to consider surgery before pregnancy. Wondering whether there’s any issue getting the treatment
